+# Dev Mode - Debugging & Development Guide
+
+Development modes provide powerful debugging and testing capabilities for container creation and installation processes.
+
+## Quick Start
+
+```bash
+# Single mode
+export dev_mode="motd"
+bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/wallabag.sh)"
+
+# Multiple modes (comma-separated)
+export dev_mode="motd,keep,trace"
+bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/wallabag.sh)"
+
+# Combine with verbose output
+export var_verbose="yes"
+export dev_mode="pause,logs"
+bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/wallabag.sh)"
+```
+
+## Available Modes
+
+### 1. **motd** - Early SSH/MOTD Setup
+
+Sets up SSH access and MOTD **before** the main application installation.
+
+**Use Case**:
+
+- Quick access to container for manual debugging
+- Continue installation manually if something goes wrong
+- Verify container networking before main install
+
+**Behavior**:
+
+```
+✔ Container created
+✔ Network configured
+[DEV] Setting up MOTD and SSH before installation
+✔ [DEV] MOTD/SSH ready - container accessible
+# Container is now accessible via SSH while installation proceeds
+```
+
+**Combined with**: `keep`, `breakpoint`, `logs`
+
+---
+
+### 2. **keep** - Preserve Container on Failure
+
+Never delete the container when installation fails. Skips cleanup prompt.
+
+**Use Case**:
+
+- Repeated tests of the same installation
+- Debugging failed installations
+- Manual fix attempts
+
+**Behavior**:
+
+```
+✖ Installation failed in container 107 (exit code: 1)
+✔ Container creation log: /tmp/create-lxc-107-abc12345.log
+✔ Installation log: /tmp/install-lxc-107-abc12345.log
+
+🔧 [DEV] Keep mode active - container 107 preserved
+root@proxmox:~#
+```
+
+**Container remains**: `pct enter 107` to access and debug
+
+**Combined with**: `motd`, `trace`, `logs`
+
+---
+
+### 3. **trace** - Bash Command Tracing
+
+Enables `set -x` for complete command-line tracing. Shows every command before execution.
+
+**Use Case**:
+
+- Deep debugging of installation logic
+- Understanding script flow
+- Identifying where errors occur exactly
+
+**Behavior**:
+
+```
++(/opt/wallabag/bin/console): /opt/wallabag/bin/console cache:warmup
++(/opt/wallabag/bin/console): env APP_ENV=prod /opt/wallabag/bin/console cache:warmup
++(/opt/wallabag/bin/console): [[ -d /opt/wallabag/app/cache ]]
++(/opt/wallabag/bin/console): rm -rf /opt/wallabag/app/cache/*
+```
+
+**⚠️ Warning**: Exposes passwords and secrets in log output! Only use in isolated environments.
+
+**Log Output**: All trace output saved to logs (see `logs` mode)
+
+**Combined with**: `keep`, `pause`, `logs`
+
+---
+
+### 4. **pause** - Step-by-Step Execution
+
+Pauses after each major step (`msg_info`). Requires manual Enter press to continue.
+
+**Use Case**:
+
+- Inspect container state between steps
+- Understand what each step does
+- Identify which step causes problems
+
+**Behavior**:
+
+```
+⏳ Setting up Container OS
+[PAUSE] Press Enter to continue...
+⏳ Updating Container OS
+[PAUSE] Press Enter to continue...
+⏳ Installing Dependencies
+[PAUSE] Press Enter to continue...
+```
+
+**Between pauses**: You can open another terminal and inspect the container
+
+```bash
+# In another terminal while paused
+pct enter 107
+root@container:~# df -h  # Check disk usage
+root@container:~# ps aux # Check running processes
+```
+
+**Combined with**: `motd`, `keep`, `logs`
+
+---
+
+### 5. **breakpoint** - Interactive Shell on Error
+
+Opens interactive shell inside the container when an error occurs instead of cleanup prompt.
+
+**Use Case**:
+
+- Live debugging in the actual container
+- Manual command testing
+- Inspect container state at point of failure
+
+**Behavior**:
+
+```
+✖ Installation failed in container 107 (exit code: 1)
+✔ Container creation log: /tmp/create-lxc-107-abc12345.log
+✔ Installation log: /tmp/install-lxc-107-abc12345.log
+
+🐛 [DEV] Breakpoint mode - opening shell in container 107
+Type 'exit' to return to host
+root@wallabag:~#
+
+# Now you can debug:
+root@wallabag:~# tail -f /root/.install-abc12345.log
+root@wallabag:~# mysql -u root -p$PASSWORD wallabag
+root@wallabag:~# apt-get install -y strace
+root@wallabag:~# exit
+
+Container 107 still running. Remove now? (y/N): n
+🔧 Container 107 kept for debugging
+```
+
+**Combined with**: `keep`, `logs`, `trace`
+
+---
+
+### 6. **logs** - Persistent Logging
+
+Saves all logs to `/var/log/community-scripts/` with timestamps. Logs persist even on successful installation.
+
+**Use Case**:
+
+- Post-mortem analysis
+- Performance analysis
+- Automated testing with log collection
+- CI/CD integration
+
+**Behavior**:
+
+```
+Logs location: /var/log/community-scripts/
+
+create-lxc-abc12345-20251117_143022.log    (host-side creation)
+install-abc12345-20251117_143022.log       (container-side installation)
+```
+
+**Access logs**:
+
+```bash
+# View creation log
+tail -f /var/log/community-scripts/create-lxc-*.log
+
+# Search for errors
+grep ERROR /var/log/community-scripts/*.log
+
+# Analyze performance
+grep "msg_info\|msg_ok" /var/log/community-scripts/create-*.log
+```
+
+**With trace mode**: Creates detailed trace of all commands
+
+```bash
+grep "^+" /var/log/community-scripts/install-*.log
+```
+
+**Combined with**: All other modes (recommended for CI/CD)
+
+---
+
+### 7. **dryrun** - Simulation Mode
+
+Shows all commands that would be executed without actually running them.
+
+**Use Case**:
+
+- Test script logic without making changes
+- Verify command syntax
+- Understand what will happen
+- Pre-flight checks
+
+**Behavior**:
+
+```
+[DRYRUN] apt-get update
+[DRYRUN] apt-get install -y curl
+[DRYRUN] mkdir -p /opt/wallabag
+[DRYRUN] cd /opt/wallabag
+[DRYRUN] git clone https://github.com/wallabag/wallabag.git .
+```
+
+**No actual changes made**: Container/system remains unchanged
+
+**Combined with**: `trace` (shows dryrun trace), `logs` (shows what would run)
+
+---
+
+## Mode Combinations
+
+### Development Workflow
+
+```bash
+# First test: See what would happen
+export dev_mode="dryrun,logs"
+bash -c "$(curl ...)"
+
+# Then test with tracing and pauses
+export dev_mode="pause,trace,logs"
+bash -c "$(curl ...)"
+
+# Finally full debug with early SSH access
+export dev_mode="motd,keep,breakpoint,logs"
+bash -c "$(curl ...)"
+```
+
+### CI/CD Integration
+
+```bash
+# Automated testing with full logging
+export dev_mode="logs"
+export var_verbose="yes"
+bash -c "$(curl ...)"
+
+# Capture logs for analysis
+tar czf installation-logs-$(date +%s).tar.gz /var/log/community-scripts/
+```
+
+### Production-like Testing
+
+```bash
+# Keep containers for manual verification
+export dev_mode="keep,logs"
+for i in {1..5}; do
+  bash -c "$(curl ...)"
+done
+
+# Inspect all created containers
+pct list
+pct enter 100
+```
+
+### Live Debugging
+
+```bash
+# SSH in early, step through installation, debug on error
+export dev_mode="motd,pause,breakpoint,keep"
+bash -c "$(curl ...)"
+```
+
+---
+
+## Environment Variables Reference
+
+### Dev Mode Variables
+
+- `dev_mode` (string): Comma-separated list of modes
+  - Format: `"motd,keep,trace"`
+  - Default: Empty (no dev modes)
+
+### Output Control
+
+- `var_verbose="yes"`: Show all command output (disables silent mode)
+  - Pairs well with: `trace`, `pause`, `logs`
+
+### Examples with vars
+
+```bash
+# Maximum verbosity and debugging
+export var_verbose="yes"
+export dev_mode="motd,trace,pause,logs"
+bash -c "$(curl ...)"
+
+# Silent debug (logs only)
+export dev_mode="keep,logs"
+bash -c "$(curl ...)"
+
+# Interactive debugging
+export var_verbose="yes"
+export dev_mode="motd,breakpoint"
+bash -c "$(curl ...)"
+```
+
+---
+
+## Troubleshooting with Dev Mode
+
+### "Installation failed at step X"
+
+```bash
+export dev_mode="pause,logs"
+# Step through until the failure point
+# Check container state between pauses
+pct enter 107
+```
+
+### "Password/credentials not working"
+
+```bash
+export dev_mode="motd,keep,trace"
+# With trace mode, see exact password handling (be careful with logs!)
+# Use motd to SSH in and test manually
+ssh root@container-ip
+```
+
+### "Permission denied errors"
+
+```bash
+export dev_mode="breakpoint,keep"
+# Get shell at failure point
+# Check file permissions, user context, SELinux status
+ls -la /path/to/file
+whoami
+```
+
+### "Networking issues"
+
+```bash
+export dev_mode="motd"
+# SSH in with motd mode before main install
+ssh root@container-ip
+ping 8.8.8.8
+nslookup example.com
+```
+
+### "Need to manually complete installation"
+
+```bash
+export dev_mode="motd,keep"
+# Container accessible via SSH while installation runs
+# After failure, SSH in and manually continue
+ssh root@container-ip
+# ... manual commands ...
+exit
+# Then use 'keep' mode to preserve container for inspection
+```
+
+---
+
+## Log Files Locations
+
+### Default (without `logs` mode)
+
+- Host creation: `/tmp/create-lxc-<SESSION_ID>.log`
+- Container install: Copied to `/tmp/install-lxc-<CTID>-<SESSION_ID>.log` on failure
+
+### With `logs` mode
+
+- Host creation: `/var/log/community-scripts/create-lxc-<SESSION_ID>-<TIMESTAMP>.log`
+- Container install: `/var/log/community-scripts/install-<SESSION_ID>-<TIMESTAMP>.log`
+
+### View logs
+
+```bash
+# Tail in real-time
+tail -f /var/log/community-scripts/*.log
+
+# Search for errors
+grep -r "exit code [1-9]" /var/log/community-scripts/
+
+# Filter by session
+grep "ed563b19" /var/log/community-scripts/*.log
+```
+
+---
+
+## Best Practices
+
+### ✅ DO
+
+- Use `logs` mode for CI/CD and automated testing
+- Use `motd` for early SSH access during long installations
+- Use `pause` when learning the installation flow
+- Use `trace` when debugging logic issues (watch for secrets!)
+- Combine modes for comprehensive debugging
+- Archive logs after successful tests
+
+### ❌ DON'T
+
+- Use `trace` in production or with untrusted networks (exposes secrets)
+- Leave `keep` mode enabled for unattended scripts (containers accumulate)
+- Use `dryrun` and expect actual changes
+- Commit `dev_mode` exports to production deployment scripts
+- Use `breakpoint` in non-interactive environments (will hang)
+
+---
+
+## Examples
+
+### Example 1: Debug a Failed Installation
+
+```bash
+# Initial test to see the failure
+export dev_mode="keep,logs"
+bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/wallabag.sh)"
+
+# Container 107 kept, check logs
+tail /var/log/community-scripts/install-*.log
+
+# SSH in to debug
+pct enter 107
+root@wallabag:~# cat /root/.install-*.log | tail -100
+root@wallabag:~# apt-get update  # Retry the failing command
+root@wallabag:~# exit
+
+# Re-run with manual step-through
+export dev_mode="motd,pause,keep"
+bash -c "$(curl ...)"
+```
+
+### Example 2: Verify Installation Steps
+
+```bash
+export dev_mode="pause,logs"
+export var_verbose="yes"
+bash -c "$(curl ...)"
+
+# Press Enter through each step
+# Monitor container in another terminal
+# pct enter 107
+# Review logs in real-time
+```
+
+### Example 3: CI/CD Pipeline Integration
+
+```bash
+#!/bin/bash
+export dev_mode="logs"
+export var_verbose="no"
+
+for app in wallabag nextcloud wordpress; do
+  echo "Testing $app installation..."
+  APP="$app" bash -c "$(curl ...)" || {
+    echo "FAILED: $app"
+    tar czf logs-$app.tar.gz /var/log/community-scripts/
+    exit 1
+  }
+  echo "SUCCESS: $app"
+done
+
+echo "All installations successful"
+tar czf all-logs.tar.gz /var/log/community-scripts/
+```
+
+---
+
+## Advanced Usage
+
+### Custom Log Analysis
+
+```bash
+# Extract all errors
+grep "ERROR\|exit code [1-9]" /var/log/community-scripts/*.log
+
+# Performance timeline
+grep "^$(date +%Y-%m-%d)" /var/log/community-scripts/*.log | grep "msg_"
+
+# Memory usage during install
+grep "free\|available" /var/log/community-scripts/*.log
+```
+
+### Integration with External Tools
+
+```bash
+# Send logs to Elasticsearch
+curl -X POST "localhost:9200/installation-logs/_doc" \
+  -H 'Content-Type: application/json' \
+  -d @/var/log/community-scripts/install-*.log
+
+# Archive for compliance
+tar czf installation-records-$(date +%Y%m).tar.gz \
+  /var/log/community-scripts/
+gpg --encrypt installation-records-*.tar.gz
+```
+
+---
+
+## Support & Issues
+
+When reporting installation issues, always include:
+
+```bash
+# Collect all relevant information
+export dev_mode="logs"
+# Run the failing installation
+# Then provide:
+tar czf debug-logs.tar.gz /var/log/community-scripts/
+```
+
+Include the `debug-logs.tar.gz` when reporting issues for better diagnostics.

+
+---
+
+## Special Case: Debian 13.1 "unsupported version" Error
+
+### Problem
+
+```
+TASK ERROR: unable to create CT 129 - unsupported debian version '13.1'
+```
+
+### Root Cause
+
+Outdated `pve-container` package doesn't recognize Debian 13 (Trixie).
+
+### Solutions
+
+#### Option 1: Full System Upgrade (Recommended)
+
+```bash
+apt update
+apt full-upgrade -y
+reboot
+```
+
+Verify fix:
+
+```bash
+dpkg -l pve-container
+# PVE 8: Should show 5.3.3+
+# PVE 9: Should show 6.0.13+
+```
+
+#### Option 2: Update Only pve-container
+
+```bash
+apt update
+apt install --only-upgrade pve-container -y
+```
+
+**Warning:** If Proxmox fails to boot after this, your system was inconsistent. Perform Option 1 instead.
+
+#### Option 3: Verify Repository Configuration
+
+Many users disable Enterprise repos but forget to add no-subscription repos.
+
+**For PVE 9 (Trixie):**
+
+```bash
+cat /etc/apt/sources.list.d/pve-no-subscription.list
+```
+
+Should contain:
+
+```
+deb http://download.proxmox.com/debian/pve trixie pve-no-subscription
+deb http://download.proxmox.com/debian/ceph-squid trixie no-subscription
+```
+
+**For PVE 8 (Bookworm):**
+
+```
+deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription
+deb http://download.proxmox.com/debian/ceph-quincy bookworm no-subscription
+```
+
+Then:
+
+```bash
+apt update
+apt full-upgrade -y
+```

+
+## Troubleshooting Tips
+
+### Finding Error Details
+
+1. **Check logs:**
+
+   ```bash
+   tail -n 50 /tmp/pct_create_*.log
+   ```
+
+2. **Enable verbose mode:**
+
+   ```bash
+   bash -x script.sh  # Shows every command executed
+   ```
+
+3. **Check container status:**
+
+   ```bash
+   pct list
+   pct status CTID
+   ```
+
+4. **Verify storage:**
+   ```bash
+   pvesm status
+   df -h
+   ```
+
+### Common Patterns
+
+- **Exit 0 with error message:** Configuration validation failed (check DNS, MAC, password format)
+- **Exit 206 but container not visible:** Ghost container state - check `/etc/pve/lxc/` manually
+- **Exit 209 generic error:** Check `/tmp/pct_create_*.log` for specific `pct create` failure reason
+- **Exit 218 or 222:** Template issues - delete and re-download template

+## File Format Specifications
+
+### User Defaults: `default.vars`
+
+**Location**: `/usr/local/community-scripts/default.vars`
+
+**MIME Type**: `text/plain`
+
+**Encoding**: UTF-8 (no BOM)
+
+**Format Specification**:
+
+```
+# File Format: Simple key=value pairs
+# Purpose: Store global user defaults
+# Security: Sanitized values, whitelist validation
+
+# Comments and blank lines are ignored
+# Line format: var_name=value
+# No spaces around the equals sign
+# String values do not need quoting (but may be quoted)
+
+[CONTENT]
+var_cpu=4
+var_ram=2048
+var_disk=20
+var_hostname=mydefault
+var_brg=vmbr0
+var_gateway=192.168.1.1
+```
+
+**Formal Grammar**:
+
+```
+FILE       := (BLANK_LINE | COMMENT_LINE | VAR_LINE)*
+BLANK_LINE := \n
+COMMENT_LINE := '#' [^\n]* \n
+VAR_LINE   := VAR_NAME '=' VAR_VALUE \n
+VAR_NAME   := 'var_' [a-z_]+
+VAR_VALUE  := [^\n]*  # Any printable characters except newline
+```
+
+**Constraints**:
+
+| Constraint        | Value                    |
+| ----------------- | ------------------------ |
+| Max file size     | 64 KB                    |
+| Max line length   | 1024 bytes               |
+| Max variables     | 100                      |
+| Allowed var names | `var_[a-z_]+`            |
+| Value validation  | Whitelist + Sanitization |
+
+**Example Valid File**:
+
+```bash
+# Global User Defaults
+# Created: 2024-11-28
+
+# Resource defaults
+var_cpu=4
+var_ram=2048
+var_disk=20
+
+# Network defaults
+var_brg=vmbr0
+var_gateway=192.168.1.1
+var_mtu=1500
+var_vlan=100
+
+# System defaults
+var_timezone=Europe/Berlin
+var_hostname=default-container
+
+# Storage
+var_container_storage=local
+var_template_storage=local
+
+# Security
+var_ssh=yes
+var_protection=0
+var_unprivileged=1
+```
+
+### App Defaults: `<app>.vars`
+
+**Location**: `/usr/local/community-scripts/defaults/<appname>.vars`
+
+**Format**: Identical to `default.vars`
+
+**Naming Convention**: `<nsapp>.vars`
+
+- `nsapp` = lowercase app name with spaces removed
+- Examples:
+  - `pihole` → `pihole.vars`
+  - `opnsense` → `opnsense.vars`
+  - `docker compose` → `dockercompose.vars`
+
+**Example App Defaults**:
+
+```bash
+# App-specific defaults for PiHole (pihole)
+# Generated on 2024-11-28T15:32:00Z
+# These override user defaults when installing pihole
+
+var_unprivileged=1
+var_cpu=2
+var_ram=1024
+var_disk=10
+var_brg=vmbr0
+var_net=veth
+var_gateway=192.168.1.1
+var_hostname=pihole
+var_timezone=Europe/Berlin
+var_container_storage=local
+var_template_storage=local
+var_tags=dns,pihole
+```

+
+## Function Reference
+
+### `load_vars_file()`
+
+**Purpose**: Safely load variables from .vars files without using `source` or `eval`
+
+**Signature**:
+
+```bash
+load_vars_file(filepath)
+```
+
+**Parameters**:
+
+| Param    | Type   | Required | Example                                     |
+| -------- | ------ | -------- | ------------------------------------------- |
+| filepath | String | Yes      | `/usr/local/community-scripts/default.vars` |
+
+**Returns**:
+
+- `0` on success
+- `1` on error (file missing, parse error, etc.)
+
+**Environment Side Effects**:
+
+- Sets all parsed `var_*` variables as shell variables
+- Does NOT unset variables if file missing (safe)
+- Does NOT affect other variables
+
+**Implementation Pattern**:
+
+```bash
+load_vars_file() {
+  local file="$1"
+
+  # File must exist
+  [ -f "$file" ] || return 0
+
+  # Parse line by line (not with source/eval)
+  local line key val
+  while IFS='=' read -r key val || [ -n "$key" ]; do
+    # Skip comments and empty lines
+    [[ "$key" =~ ^[[:space:]]*# ]] && continue
+    [[ -z "$key" ]] && continue
+
+    # Validate key is in whitelist
+    _is_whitelisted_key "$key" || continue
+
+    # Sanitize and export value
+    val="$(_sanitize_value "$val")"
+    [ $? -eq 0 ] && export "$key=$val"
+  done < "$file"
+
+  return 0
+}
+```
+
+**Usage Examples**:
+
+```bash
+# Load user defaults
+load_vars_file "/usr/local/community-scripts/default.vars"
+
+# Load app-specific defaults
+load_vars_file "$(get_app_defaults_path)"
+
+# Check if successful
+if load_vars_file "$vars_path"; then
+  echo "Settings loaded successfully"
+else
+  echo "Failed to load settings"
+fi
+
+# Values are now available as variables
+echo "Using $var_cpu cores"
+echo "Allocating ${var_ram} MB RAM"
+```

+- String: Full path to app defaults file
+
+**Implementation**:
+
+```bash
+get_app_defaults_path() {
+  local n="${NSAPP:-${APP,,}}"
+  echo "/usr/local/community-scripts/defaults/${n}.vars"
+}
+```
+
+**Usage Examples**:
+
+```bash
+# Get app defaults path
+app_defaults="$(get_app_defaults_path)"
+echo "App defaults at: $app_defaults"

+---
+
+### `default_var_settings()`
+
+**Purpose**: Load and display user global defaults
+
+**Signature**:
+
+```bash
+default_var_settings()
+```
+
+**Parameters**: None
+
+**Returns**:
+
+- `0` on success
+- `1` on error
+
+**Workflow**:
+
+```
+1. Find default.vars location
+   (usually /usr/local/community-scripts/default.vars)
+
+2. Create if missing
+
+3. Load variables from file
+
+4. Map var_verbose → VERBOSE variable
+
+5. Call base_settings (apply to container config)
+
+6. Call echo_default (display summary)
+```
+
+**Implementation Pattern**:
+
+```bash
+default_var_settings() {
+  local VAR_WHITELIST=(
+    var_apt_cacher var_apt_cacher_ip var_brg var_cpu var_disk var_fuse var_gpu
+    var_gateway var_hostname var_ipv6_method var_mac var_mtu
+    var_net var_ns var_pw var_ram var_tags var_tun var_unprivileged
+    var_verbose var_vlan var_ssh var_ssh_authorized_key
+    var_container_storage var_template_storage
+  )
+
+  # Ensure file exists
+  _ensure_default_vars
+
+  # Find and load
+  local dv="$(_find_default_vars)"
+  load_vars_file "$dv"
+
+  # Map verbose flag
+  if [[ -n "${var_verbose:-}" ]]; then
+    case "${var_verbose,,}" in
+      1 | yes | true | on) VERBOSE="yes" ;;
+      *) VERBOSE="${var_verbose}" ;;
+    esac
+  fi
+
+  # Apply and display
+  base_settings "$VERBOSE"
+  echo_default
+}
+```
+
+---
+
+### `maybe_offer_save_app_defaults()`
+
+**Purpose**: Offer to save current settings as app-specific defaults
+
+**Signature**:
+
+```bash
+maybe_offer_save_app_defaults()
+```
+
+**Parameters**: None
+
+**Returns**: None (side effects only)
+
+**Behavior**:
+
+1. After advanced installation completes
+2. Offers user: "Save as App Defaults for <APP>?"
+3. If yes:
+   - Saves to `/usr/local/community-scripts/defaults/<app>.vars`
+   - Only whitelisted variables included
+   - Previous defaults backed up (if exists)
+4. If no:
+   - No action taken
+
+**Flow**:
+
+```bash
+maybe_offer_save_app_defaults() {
+  local app_vars_path="$(get_app_defaults_path)"
+
+  # Build current settings from memory
+  local new_tmp="$(_build_current_app_vars_tmp)"
+
+  # Check if already exists
+  if [ -f "$app_vars_path" ]; then
+    # Show diff and ask: Update? Keep? View Diff?
+    _show_app_defaults_diff_menu "$new_tmp" "$app_vars_path"
+  else
+    # New defaults - just save
+    if whiptail --yesno "Save as App Defaults for $APP?" 10 60; then
+      mv "$new_tmp" "$app_vars_path"
+      chmod 644 "$app_vars_path"
+    fi
+  fi
+}
+```
+
+---
+

+
+**Dangerous Patterns**:
+
+| Pattern   | Threat               | Example              |
+| --------- | -------------------- | -------------------- |
+| `$(...)`  | Command substitution | `$(rm -rf /)`        |
+| `` ` ` `` | Command substitution | `` `whoami` ``       |

+  return 0
+}
+```
+
+**Usage Examples**:
+
+```bash
+# Safe value
+_sanitize_value "192.168.1.1"  # Returns: 192.168.1.1 (status: 0)
+
+# Dangerous value
+_sanitize_value "$(whoami)"     # Returns: (empty) (status: 1)

+
+## Variable Precedence
+
+### Loading Order
+
+When a container is being created, variables are resolved in this order:
+
+```
+Step 1: Read ENVIRONMENT VARIABLES
+   ├─ Check if var_cpu is already set in shell environment
+   ├─ Check if var_ram is already set
+   └─ ...all var_* variables
+
+Step 2: Load APP-SPECIFIC DEFAULTS
+   ├─ Check if /usr/local/community-scripts/defaults/pihole.vars exists
+   ├─ Load all var_* from that file
+   └─ These override built-ins but NOT environment variables
+
+Step 3: Load USER GLOBAL DEFAULTS
+   ├─ Check if /usr/local/community-scripts/default.vars exists
+   ├─ Load all var_* from that file
+   └─ These override built-ins but NOT app-specific
+
+Step 4: Use BUILT-IN DEFAULTS
+   └─ Hardcoded in script (lowest priority)
+```
+
+### Precedence Examples
+
+**Example 1: Environment Variable Wins**
+
+```bash
+# Shell environment has highest priority
+$ export var_cpu=16
+$ bash pihole-install.sh
+
+# Result: Container gets 16 cores
+# (ignores app defaults, user defaults, built-ins)
+```
+
+**Example 2: App Defaults Override User Defaults**
+
+```bash
+# User Defaults: var_cpu=4
+# App Defaults: var_cpu=2
+$ bash pihole-install.sh
+
+# Result: Container gets 2 cores
+# (app-specific setting takes precedence)
+```
+
+**Example 3: All Defaults Missing (Built-ins Used)**
+
+```bash
+# No environment variables set
+# No app defaults file
+# No user defaults file
+$ bash pihole-install.sh
+
+# Result: Uses built-in defaults
+# (var_cpu might be 2 by default)
+```
+
+### Implementation in Code
+
+```bash
+# Typical pattern in build.func
+
+base_settings() {
+  # Priority 1: Environment variables (already set if export used)
+  CT_TYPE=${var_unprivileged:-"1"}          # Use existing or default
+
+  # Priority 2: Load app defaults (may override above)
+  if [ -f "$(get_app_defaults_path)" ]; then
+    load_vars_file "$(get_app_defaults_path)"
+  fi
+
+  # Priority 3: Load user defaults
+  if [ -f "/usr/local/community-scripts/default.vars" ]; then
+    load_vars_file "/usr/local/community-scripts/default.vars"
+  fi
+
+  # Priority 4: Apply built-in defaults (lowest)
+  CORE_COUNT=${var_cpu:-"${APP_CPU_DEFAULT:-2}"}
+  RAM_SIZE=${var_ram:-"${APP_RAM_DEFAULT:-1024}"}
+
+  # Result: var_cpu has been set through precedence chain
+}

+## Security Model
+
+### Threat Model
+
+| Threat                       | Mitigation                                        |
+| ---------------------------- | ------------------------------------------------- |
+| **Arbitrary Code Execution** | No `source` or `eval`; manual parsing only        |
+| **Variable Injection**       | Whitelist of allowed variable names               |
+| **Command Substitution**     | `_sanitize_value()` blocks `$()`, backticks, etc. |
+| **Path Traversal**           | Files locked to `/usr/local/community-scripts/`   |
+| **Permission Escalation**    | Files created with restricted permissions         |
+| **Information Disclosure**   | Sensitive variables not logged                    |
+
+### Security Controls
+
+#### 1. Input Validation
+
+```bash
+# Only specific variables allowed
+if ! _is_whitelisted_key "$key"; then
+  skip_this_variable
+fi
+
+# Values sanitized
+if ! val="$(_sanitize_value "$value")"; then
+  reject_entire_line
+fi
+```
+
+#### 2. Safe File Parsing
+
+```bash
+# ❌ DANGEROUS (OLD)
+source /path/to/config.conf
+# Could execute: rm -rf / or any code
+
+# ✅ SAFE (NEW)
+load_vars_file "/path/to/config.conf"
+# Only reads var_name=value pairs, no execution
+```
+
+#### 3. Whitelisting
+
+```bash
+# Only these variables can be configured
+var_cpu, var_ram, var_disk, var_brg, ...
+var_hostname, var_pw, var_ssh, ...
+
+# NOT allowed:
+var_malicious, var_hack, custom_var, ...
+```
+
+#### 4. Value Constraints
+
+```bash
+# No command injection patterns
+if [[ "$value" =~ ($|`|;|&|<\() ]]; then
+  reject_value
+fi
+```
+
+---
+
+## Implementation Details
+
+### Module: `build.func`
+
+**Load Order** (in actual scripts):
+
+1. `#!/usr/bin/env bash` - Shebang
+2. `source /dev/stdin <<<$(curl ... api.func)` - API functions
+3. `source /dev/stdin <<<$(curl ... build.func)` - Build functions
+4. `variables()` - Initialize variables
+5. `check_root()` - Security check
+6. `install_script()` - Main flow
+
+**Key Sections**:
+
+```bash
+# Section 1: Initialization & Variables
+- variables()
+- NSAPP, var_install, INTEGER pattern, etc.
+
+# Section 2: Storage Management
+- storage_selector()
+- ensure_storage_selection_for_vars_file()
+
+# Section 3: Base Settings
+- base_settings()          # Apply defaults to all var_*
+- echo_default()           # Display current settings
+
+# Section 4: Variable Loading
+- load_vars_file()         # Safe parsing
+- _is_whitelisted_key()    # Validation
+- _sanitize_value()        # Threat mitigation
+
+# Section 5: Defaults Management
+- default_var_settings()   # Load user defaults
+- get_app_defaults_path()  # Get app defaults path
+- maybe_offer_save_app_defaults()  # Save option
+
+# Section 6: Installation Flow
+- install_script()         # Main entry point
+- advanced_settings()      # 20-step wizard
+```

+### Regex Patterns Used
+
+| Pattern                | Purpose               | Example Match           |
+| ---------------------- | --------------------- | ----------------------- |
+| `^[0-9]+([.][0-9]+)?$` | Integer validation    | `4`, `192.168`          |
+| `^var_[a-z_]+$`        | Variable name         | `var_cpu`, `var_ssh`    |
+| `*'$('*`               | Command substitution  | `$(whoami)`             |
+| `*\`\*`                | Backtick substitution | `` `cat /etc/passwd` `` |
+
+---
+
+## Appendix: Migration Reference
+
+### Old Pattern (Deprecated)
+
+```bash
+# ❌ OLD: config-file.func
+source config-file.conf          # Executes arbitrary code
+if [ "$USE_DEFAULTS" = "yes" ]; then
+  apply_settings_directly
+fi
+```
+
+### New Pattern (Current)
+
+```bash
+# ✅ NEW: load_vars_file()
+if load_vars_file "$(get_app_defaults_path)"; then
+  echo "Settings loaded securely"
+fi
+```
+
+### Function Mapping
+
+| Old              | New                               | Location   |
+| ---------------- | --------------------------------- | ---------- |
+| `read_config()`  | `load_vars_file()`                | build.func |

+# API Integration Documentation (/api)
+
+This directory contains comprehensive documentation for API integration and the `/api` directory.
+
+## Overview
+
+The `/api` directory contains the Proxmox Community Scripts API backend for diagnostic reporting, telemetry, and analytics integration.
+
+## Key Components
+
+### Main API Service
+Located in `/api/main.go`:
+- RESTful API for receiving telemetry data
+- Installation statistics tracking
+- Error reporting and analytics
+- Performance monitoring
+
+### Integration with Scripts
+The API is integrated into all installation scripts via `api.func`:
+- Sends installation start/completion events
+- Reports errors and exit codes
+- Collects anonymous usage statistics
+- Enables project analytics
+
+## Documentation Structure
+
+API documentation covers:
+- API endpoint specifications
+- Integration methods
+- Data formats and schemas
+- Error handling
+- Privacy and data handling
+
+## Key Resources
+
+- **[misc/api.func/](../misc/api.func/)** - API function library documentation
+- **[misc/api.func/README.md](../misc/api.func/README.md)** - Quick reference
+- **[misc/api.func/API_FUNCTIONS_REFERENCE.md](../misc/api.func/API_FUNCTIONS_REFERENCE.md)** - Complete function reference
+
+## API Functions
+
+The `api.func` library provides:
+
+### `post_to_api()`
+Send container installation data to API.
+
+**Usage**:
+```bash
+post_to_api CTID STATUS APP_NAME
+```
+
+### `post_update_to_api()`
+Report application update status.
+
+**Usage**:
+```bash
+post_update_to_api CTID APP_NAME VERSION
+```
+
+### `get_error_description()`
+Get human-readable error description from exit code.
+
+**Usage**:
+```bash
+ERROR_DESC=$(get_error_description EXIT_CODE)
+```
+
+## API Integration Points
+
+### In Container Creation (`ct/AppName.sh`)
+- Called by build.func to report container creation
+- Sends initial container setup data
+- Reports success or failure
+
+### In Installation Scripts (`install/appname-install.sh`)
+- Called at start of installation
+- Called on installation completion
+- Called on error conditions
+
+### Data Collected
+- Container/VM ID
+- Application name and version
+- Installation duration
+- Success/failure status
+- Error codes (if failure)
+- Anonymous usage metrics
+
+## Privacy
+
+All API data:
+- ✅ Anonymous (no personal data)
+- ✅ Aggregated for statistics
+- ✅ Used only for project improvement
+- ✅ No tracking of user identities
+- ✅ Can be disabled if desired
+
+## API Architecture
+
+```
+Installation Scripts
+    │
+    ├─ Call: api.func functions
+    │
+    └─ POST to: https://api.community-scripts.org
+                │
+                ├─ Receives data
+                ├─ Validates format
+                ├─ Stores metrics
+                └─ Aggregates statistics
+                    │
+                    └─ Used for:
+                       ├─ Download tracking
+                       ├─ Error trending
+                       ├─ Feature usage stats
+                       └─ Project health monitoring
+```
+
+## Common API Tasks
+
+- **Enable API reporting** → Built-in by default, no configuration needed
+- **Disable API** → Set `api_disable="yes"` before running
+- **View API data** → Visit https://community-scripts.org/stats
+- **Report API errors** → [GitHub Issues](https://github.com/community-scripts/ProxmoxVE/issues)
+
+## Debugging API Issues
+
+If API calls fail:
+1. Check internet connectivity
+2. Verify API endpoint availability
+3. Review error codes in [EXIT_CODES.md](../EXIT_CODES.md)
+4. Check API function logs
+5. Report issues on GitHub
+
+## API Endpoint
+
+**Base URL**: `https://api.community-scripts.org`
+
+**Endpoints**:
+- `POST /install` - Report container installation
+- `POST /update` - Report application update
+- `GET /stats` - Public statistics

+
+## Common Workflows
+
+### Keep Your Fork Updated
+```bash
+# Add upstream if you haven't already
+git remote add upstream https://github.com/community-scripts/ProxmoxVE.git
+
+# Get latest from upstream
+git fetch upstream
+git rebase upstream/main
+git push origin main
+```
+
+### Create a Feature Branch
+```bash
+git checkout -b feature/docker-improvements
+# Make changes...
+git push origin feature/docker-improvements
+# Then create PR on GitHub
+```
+
+### Sync Before Contributing
+```bash
+git fetch upstream
+git rebase upstream/main
+git push -f origin main  # Update your fork's main
+git checkout -b feature/my-feature
+```
+
+---
+
+## Troubleshooting
+
+### "Git is not installed" or "not a git repository"
+```bash
+# Make sure you cloned the repo first
+git clone https://github.com/YOUR_USERNAME/ProxmoxVE.git
+cd ProxmoxVE
+bash setup-fork.sh
+```
+
+### "Could not auto-detect GitHub username"
+```bash
+# Your git origin URL isn't set up correctly
+git remote -v
+# Should show your fork URL, not community-scripts
+
+# Fix it:
+git remote set-url origin https://github.com/YOUR_USERNAME/ProxmoxVE.git
+bash setup-fork.sh
+```
+
+### "Permission denied"
+```bash
+# Make script executable
+chmod +x setup-fork.sh
+bash setup-fork.sh
+```
+
+### Reverted Changes by Accident?
+```bash
+# Backups are created automatically
+git checkout docs/*.backup
+# Or just re-run setup-fork.sh
+```
+
+---
+
+## Next Steps
+
+1. ✅ Run `bash setup-fork.sh`
+2. 📖 Read [docs/CONTRIBUTION_GUIDE.md](docs/CONTRIBUTION_GUIDE.md)

+
+## 🚀 Quick Start
+
+### 60 Seconds to Contributing
+
+```bash
+# 1. Fork on GitHub
+# Visit: https://github.com/community-scripts/ProxmoxVE → Fork (top right)
+
+# 2. Clone your fork
+git clone https://github.com/YOUR_USERNAME/ProxmoxVE.git
+cd ProxmoxVE
+
+# 3. Auto-configure your fork
+bash docs/contribution/setup-fork.sh
+
+# 4. Create a feature branch
+git checkout -b feature/my-awesome-app
+
+# 5. Read the guides
+cat docs/README.md              # Documentation overview

+git commit -m "feat: add MyApp"
+git push origin feature/my-awesome-app
+
+# 8. Create Pull Request on GitHub
+```
+
+---
+
+## 🍴 Setting Up Your Fork
+
+### Automatic Setup (Recommended)
+
+When you clone your fork, run the setup script to automatically configure everything:
+
+```bash
+bash docs/contribution/setup-fork.sh
+```
+
+This will:
+- Auto-detect your GitHub username
+- Update all documentation links to point to your fork
+- Create `.git-setup-info` with recommended git workflows
+
+**See**: [FORK_SETUP.md](FORK_SETUP.md) for detailed instructions
+
+### Manual Setup
+
+If the script doesn't work, manually configure:
+
+```bash
+# Set git user
+git config user.name "Your Name"
+git config user.email "your.email@example.com"
+
+# Add upstream remote for syncing
+git remote add upstream https://github.com/community-scripts/ProxmoxVE.git
+
+# Verify remotes
+git remote -v
+```
+
+---
+

+
+## Recommended Git Configuration
+
+### Set up remotes for easy syncing with upstream:
+
+```bash
+# View your current remotes
+git remote -v
+
+# If you don't have 'upstream' configured, add it:
+git remote add upstream https://github.com/community-scripts/ProxmoxVE.git
+
+# Verify both remotes exist:
+git remote -v
+# Should show:
+# origin     https://github.com/YOUR_USERNAME/ProxmoxVE.git (fetch)
+# origin     https://github.com/YOUR_USERNAME/ProxmoxVE.git (push)
+# upstream   https://github.com/community-scripts/ProxmoxVE.git (fetch)
+# upstream   https://github.com/community-scripts/ProxmoxVE.git (push)
+```
+
+### Configure Git User (if not done globally)
+
+```bash
+git config user.name "Your Name"
+git config user.email "your.email@example.com"
+
+# Or configure globally:
+git config --global user.name "Your Name"
+git config --global user.email "your.email@example.com"
+```
+
+### Useful Git Workflows
+
+**Keep your fork up-to-date:**
+```bash
+git fetch upstream
+git rebase upstream/main
+git push origin main
+```
+
+**Create feature branch:**
+```bash
+git checkout -b feature/my-awesome-app
+# Make changes...
+git commit -m "feat: add my awesome app"
+git push origin feature/my-awesome-app
+```
+
+**Pull latest from upstream:**
+```bash
+git fetch upstream
+git merge upstream/main
+```

+
+**Modern Guide to Creating LXC Container Installation Scripts**

+
+---
+
+## Overview
+
+### Purpose
+
+Container scripts (`ct/AppName.sh`) are **entry points for creating LXC containers** with specific applications pre-installed. They:
+
+1. Define container defaults (CPU, RAM, disk, OS)
+2. Call the main build orchestrator (`build.func`)
+3. Implement application-specific update mechanisms
+4. Provide user-facing success messages
+
+### Execution Context
+
+```
+Proxmox Host
+    ↓
+ct/AppName.sh sourced (runs as root on host)
+    ↓
+build.func: Creates LXC container + runs install script inside
+    ↓
+install/AppName-install.sh (runs inside container)
+    ↓
+Container ready with app installed
+```
+
+### Key Integration Points
+
+- **build.func** - Main orchestrator (container creation, storage, variable management)
+- **install.func** - Container-specific setup (OS update, package management)
+- **tools.func** - Tool installation helpers (repositories, GitHub releases)
+- **core.func** - UI/messaging functions (colors, spinners, validation)
+- **error_handler.func** - Error handling and signal management
+
+---
+
+## Architecture & Flow
+
+### Container Creation Flow
+
+```
+START: bash ct/pihole.sh
+  ↓
+[1] Set APP, var_*, defaults
+  ↓
+[2] header_info() → Display ASCII art
+  ↓
+[3] variables() → Parse arguments & load build.func
+  ↓
+[4] color() → Setup ANSI codes
+  ↓
+[5] catch_errors() → Setup trap handlers
+  ↓
+[6] install_script() → Show mode menu (5 options)
+  ↓
+  ├─ INSTALL_MODE="0" (Default)
+  ├─ INSTALL_MODE="1" (Advanced - 19-step wizard)
+  ├─ INSTALL_MODE="2" (User Defaults)
+  ├─ INSTALL_MODE="3" (App Defaults)
+  └─ INSTALL_MODE="4" (Settings Menu)
+  ↓
+[7] advanced_settings() → Collect user configuration (if mode=1)
+  ↓
+[8] start() → Confirm or re-edit settings
+  ↓
+[9] build_container() → Create LXC + execute install script
+  ↓
+[10] description() → Set container description
+  ↓
+[11] SUCCESS → Display access URL
+  ↓
+END
+```
+
+### Default Values Precedence
+
+```
+Priority 1 (Highest): Environment Variables (var_cpu, var_ram, etc.)
+Priority 2: App-Specific Defaults (/defaults/AppName.vars)
+Priority 3: User Global Defaults (/default.vars)
+Priority 4 (Lowest): Built-in Defaults (in build.func)

+
+### 2. Application Metadata
+
+```bash
+# Application Configuration
+APP="ApplicationName"
+var_tags="tag1;tag2;tag3"      # Max 3-4 tags, no spaces, semicolon-separated
+
+# Container Resources
+var_cpu="2"                    # CPU cores
+var_ram="2048"                 # RAM in MB

+var_unprivileged="1"           # 1=unprivileged (secure), 0=privileged (rarely needed)
+```
+
+**Variable Naming Convention**:
+- Variables exposed to user: `var_*` (e.g., `var_cpu`, `var_hostname`, `var_ssh`)
+- Internal variables: lowercase (e.g., `container_id`, `app_version`)
+
+### 3. Display & Initialization
+
+```bash
+# Display header ASCII art
+header_info "$APP"
+
+# Process command-line arguments and load configuration
+variables
+
+# Setup ANSI color codes and formatting
+color
+
+# Initialize error handling (trap ERR, EXIT, INT, TERM)
+catch_errors
+```
+
+### 4. Update Function (Highly Recommended)
+
+```bash
+function update_script() {
+  header_info
+
+  # Always start with these checks
+  check_container_storage
+  check_container_resources
+
+  # Verify app is installed

+    exit
+  fi
+
+  # Get latest version from GitHub
+  RELEASE=$(curl -fsSL https://api.github.com/repos/user/repo/releases/latest | \
+    grep "tag_name" | awk '{print substr($2, 2, length($2)-3)}')
+
+  # Compare with saved version
+  if [[ ! -f /opt/${APP}_version.txt ]] || [[ "${RELEASE}" != "$(cat /opt/${APP}_version.txt)" ]]; then
+    msg_info "Updating ${APP} to v${RELEASE}"
+
+    # Backup user data
+    cp -r /opt/appname /opt/appname-backup
+
+    # Perform update
+    cd /opt
+    wget -q "https://github.com/user/repo/releases/download/v${RELEASE}/app-${RELEASE}.tar.gz"
+    tar -xzf app-${RELEASE}.tar.gz
+
+    # Restore user data
+    cp /opt/appname-backup/config/* /opt/appname/config/
+
+    # Cleanup
+    rm -rf app-${RELEASE}.tar.gz /opt/appname-backup
+
+    # Save new version
+    echo "${RELEASE}" > /opt/${APP}_version.txt
+
+    msg_ok "Updated ${APP} to v${RELEASE}"
+  else
+    msg_ok "No update required. ${APP} is already at v${RELEASE}."
+  fi
+
+  exit
+}
+```
+
+### 5. Script Launch
+
+```bash
+# Start the container creation workflow
+start
+
+# Build the container with selected configuration
+build_container
+
+# Set container description/notes in Proxmox UI
+description
+
+# Display success message
+msg_ok "Completed Successfully!\n"
+echo -e "${CREATING}${GN}${APP} setup has been successfully initialized!${CL}"
+echo -e "${INFO}${YW} Access it using the following URL:${CL}"
+echo -e "${TAB}${GATEWAY}${BGN}http://${IP}:8080${CL}"
+```
+
+---
+
+## Function Reference
+
+### Core Functions (From build.func)
+
+#### `variables()`
+
+**Purpose**: Initialize container variables, load user arguments, setup orchestration
+
+**Triggered by**: Called automatically at script start
+
+**Behavior**:
+1. Parse command-line arguments (if any)
+2. Generate random UUID for session tracking
+3. Load container storage from Proxmox
+4. Initialize application-specific defaults
+5. Setup SSH/environment configuration
+
+#### `start()`
+
+**Purpose**: Launch the container creation menu with 5 installation modes
+
+**Menu Options**:
+```
+1. Default Installation (Quick setup, predefined settings)
+2. Advanced Installation (19-step wizard with full control)
+3. User Defaults (Load ~/.community-scripts/default.vars)
+4. App Defaults (Load /defaults/AppName.vars)
+5. Settings Menu (Interactive mode selection)
+```
+
+#### `build_container()`
+
+**Purpose**: Main orchestrator for LXC container creation
+
+**Operations**:
+1. Validates all variables
+2. Creates LXC container via `pct create`
+3. Executes `install/AppName-install.sh` inside container
+4. Monitors installation progress
+5. Handles errors and rollback on failure
+
+#### `description()`
+
+**Purpose**: Set container description/notes visible in Proxmox UI
+
+---
+
+## Advanced Features
+
+### 1. Custom Configuration Menus
+
+If your app has additional setup beyond standard vars:
+
+```bash
+custom_app_settings() {
+  CONFIGURE_DB=$(whiptail --title "Database Setup" \
+    --yesno "Would you like to configure a custom database?" 8 60)
+
+  if [[ $? -eq 0 ]]; then
+    DB_HOST=$(whiptail --inputbox "Database Host:" 8 60 3>&1 1>&2 2>&3)
+    DB_PORT=$(whiptail --inputbox "Database Port:" 8 60 "3306" 3>&1 1>&2 2>&3)
+  fi
+}
+
+custom_app_settings
+```
+
+### 2. Update Function Patterns
+
+Save installed version for update checks
+
+### 3. Health Check Functions
+
+Add custom validation:
+
+```bash
+function health_check() {
+  header_info
+
+  if [[ ! -d /opt/appname ]]; then
+    msg_error "Application not found!"
+    exit 1
+  fi
+
+  if ! systemctl is-active --quiet appname; then
+    msg_error "Application service not running"
+    exit 1
+  fi
+
+  msg_ok "Health check passed"
+}
+```
+
+---
+
+## Real Examples
+
+### Example 1: Simple Web App (Debian-based)
+
+```bash
+#!/usr/bin/env bash
+source <(curl -fsSL https://git.community-scripts.org/community-scripts/ProxmoxVE/raw/branch/main/misc/build.func)
+
+APP="Homarr"
+var_tags="dashboard;homepage"
+var_cpu="2"
+var_ram="1024"
+var_disk="5"
+var_os="debian"
+var_version="12"
+var_unprivileged="1"
+
+header_info "$APP"
+variables
+color
+catch_errors
+
+function update_script() {
+  # Update logic here
+}
+
+start
+build_container
+description
+msg_ok "Completed Successfully!\n"
+```
+
+---
+
+## Troubleshooting
+
+### Container Creation Fails
+
+**Symptom**: `pct create` exits with error code 209
+
+**Solution**:
+```bash
+# Check existing containers
+pct list | grep CTID
+
+# Remove conflicting container
+pct destroy CTID
+
+# Retry ct/AppName.sh
+```
+
+### Update Function Doesn't Detect New Version
+
+**Debug**:
+```bash
+# Check version file
+cat /opt/AppName_version.txt
+
+# Test GitHub API
+curl -fsSL https://api.github.com/repos/user/repo/releases/latest | grep tag_name
+```

+- [ ] `var_tags` are semicolon-separated (no spaces)
+
+### Default Values
+- [ ] `var_cpu` set appropriately (2-4 for most apps)
+- [ ] `var_ram` set appropriately (1024-4096 MB minimum)
+- [ ] `var_disk` sufficient for app + data (5-20 GB)
+- [ ] `var_os` is realistic
+
+### Functions
+- [ ] `update_script()` implemented
+- [ ] Update function checks if app installed
+- [ ] Proper error handling with `msg_error`
+
+### Testing
+- [ ] Script tested with default installation
+- [ ] Script tested with advanced (19-step) installation
+- [ ] Update function tested on existing installation

+
+## Best Practices
+
+### ✅ DO:
+
+1. **Use meaningful defaults**
+2. **Implement version tracking**
+3. **Handle edge cases**
+4. **Use proper messaging with msg_info/msg_ok/msg_error**
+
+### ❌ DON'T:
+
+1. **Hardcode versions**
+2. **Use custom color codes** (use built-in variables)
+3. **Forget error handling**
+4. **Leave temporary files**
+

+
+## Variable Naming Convention
+
+All configuration variables follow a consistent pattern:
+
+```
+var_<setting>=<value>
+```
+
+**Rules:**
+- ✅ Always starts with `var_`
+- ✅ Lowercase letters only
+- ✅ Underscores for word separation
+- ✅ No spaces around `=`
+- ✅ Values can be quoted if needed
+
+**Examples:**
+```bash
+# ✓ Correct
+var_cpu=4
+var_hostname=myserver
+var_ssh_authorized_key=ssh-rsa AAAA...
+
+# ✗ Wrong
+CPU=4                    # Missing var_ prefix
+var_CPU=4                # Uppercase not allowed
+var_cpu = 4              # Spaces around =
+var-cpu=4                # Hyphens not allowed
+```
+
+---
+
+## Complete Variable Reference
+
+### var_unprivileged
+
+**Type:** Boolean (0 or 1)
+**Default:** `1` (unprivileged)
+**Description:** Determines if container runs unprivileged (recommended) or privileged.
+
+```bash
+var_unprivileged=1    # Unprivileged (safer, recommended)
+var_unprivileged=0    # Privileged (less secure, more features)
+```
+
+**When to use privileged (0):**
+- Hardware access required
+- Certain kernel modules needed
+- Legacy applications
+- Nested virtualization with full features
+
+**Security Impact:**
+- Unprivileged: Container root is mapped to unprivileged user on host
+- Privileged: Container root = host root (security risk)
+
+---
+
+### var_cpu
+
+**Type:** Integer
+**Default:** Varies by app (usually 1-4)
+**Range:** 1 to host CPU count
+**Description:** Number of CPU cores allocated to container.

+var_cpu=2     # Dual core (typical)
+var_cpu=4     # Quad core (recommended for apps)
+var_cpu=8     # High performance
+```
+
+**Best Practices:**
+- Start with 2 cores for most applications
+- Monitor usage with `pct exec <id> -- htop`
+- Can be changed after creation
+- Consider host CPU count (don't over-allocate)
+
+---
+
+### var_ram
+
+**Type:** Integer (MB)

+var_ram=4096     # 4 GB (recommended for databases)
+var_ram=8192     # 8 GB (high memory apps)
+```
+
+**Conversion Guide:**
+```
+512 MB   = 0.5 GB
+1024 MB  = 1 GB
+2048 MB  = 2 GB
+4096 MB  = 4 GB
+8192 MB  = 8 GB
+16384 MB = 16 GB
+```

+
+## Quick Start
+
+### 30-Second Setup
+
+```bash
+# 1. Run any container installation script
+bash pihole-install.sh
+
+# 2. When prompted, select: "Advanced Settings"
+#    (This allows you to customize everything)
+
+# 3. Answer all configuration questions
+
+# 4. At the end, when asked "Save as App Defaults?"
+#    Select: YES
+
+# 5. Done! Your settings are now saved
+```
+
+**Next Time**: Run the same script again, select **"App Defaults"** and your settings will be applied automatically!
+
+---
+
+## Understanding the Defaults System
+
+### The Three-Tier System
+
+Your installation settings are managed through three layers:
+
+#### 🔷 **Tier 1: Built-in Defaults** (Fallback)
+```
+These are hardcoded in the scripts
+Provide sensible defaults for each application
+Example: PiHole uses 2 CPU cores by default
+```
+
+#### 🔶 **Tier 2: User Defaults** (Global)
+```
+Your personal global defaults
+Applied to ALL container installations
+Location: /usr/local/community-scripts/default.vars
+Example: "I always want 4 CPU cores and 2GB RAM"
+```
+
+#### 🔴 **Tier 3: App Defaults** (Specific)
+```
+Application-specific saved settings
+Only applied when installing that specific app
+Location: /usr/local/community-scripts/defaults/<appname>.vars
+Example: "Whenever I install PiHole, use these exact settings"
+```
+
+### Priority System
+
+When installing a container, settings are applied in this order:
+
+```
+┌─────────────────────────────────────┐
+│ 1. Environment Variables (HIGHEST)  │  Set in shell: export var_cpu=8
+│    (these override everything)      │
+├─────────────────────────────────────┤
+│ 2. App Defaults                     │  From: defaults/pihole.vars
+│    (app-specific saved settings)    │
+├─────────────────────────────────────┤
+│ 3. User Defaults                    │  From: default.vars
+│    (your global defaults)           │
+├─────────────────────────────────────┤
+│ 4. Built-in Defaults (LOWEST)       │  Hardcoded in script
+│    (failsafe, always available)     │
+└─────────────────────────────────────┘
+```
+
+**In Plain English**: 
+- If you set an environment variable → it wins
+- Otherwise, if you have app-specific defaults → use those
+- Otherwise, if you have user defaults → use those
+- Otherwise, use the hardcoded defaults
+
+---
+
+## Installation Modes
+
+When you run any installation script, you'll be presented with a menu:
+
+### Option 1️⃣ : **Default Settings**
+
+```
+Quick installation with standard settings
+├─ Best for: First-time users, quick deployments
+├─ What happens:
+│  1. Script uses built-in defaults
+│  2. Container created immediately
+│  3. No questions asked
+└─ Time: ~2 minutes
+```
+
+**When to use**: You want a standard installation, don't need customization
+
+---
+
+### Option 2️⃣ : **Advanced Settings**
+
+```
+Full customization with 19 configuration steps
+├─ Best for: Power users, custom requirements
+├─ What happens:
+│  1. Script asks for EVERY setting
+│  2. You control: CPU, RAM, Disk, Network, SSH, etc.
+│  3. Shows summary before creating
+│  4. Offers to save as App Defaults
+└─ Time: ~5-10 minutes
+```
+
+**When to use**: You want full control over the configuration
+
+**Available Settings**:
+- CPU cores, RAM amount, Disk size
+- Container name, network settings
+- SSH access, API access, Features
+- Password, SSH keys, Tags
+
+---
+
+### Option 3️⃣ : **User Defaults**
+
+```
+Use your saved global defaults
+├─ Best for: Consistent deployments across many containers
+├─ Requires: You've previously saved User Defaults
+├─ What happens:
+│  1. Loads settings from: /usr/local/community-scripts/default.vars
+│  2. Shows you the loaded settings
+│  3. Creates container immediately
+└─ Time: ~2 minutes
+```
+
+**When to use**: You have preferred defaults you want to use for every app
+
+---
+
+### Option 4️⃣ : **App Defaults** (if available)
+
+```
+Use previously saved app-specific defaults
+├─ Best for: Repeating the same configuration multiple times
+├─ Requires: You've previously saved App Defaults for this app
+├─ What happens:
+│  1. Loads settings from: /usr/local/community-scripts/defaults/<app>.vars
+│  2. Shows you the loaded settings
+│  3. Creates container immediately
+└─ Time: ~2 minutes
+```
+
+**When to use**: You've installed this app before and want identical settings
+
+---
+
+### Option 5️⃣ : **Settings Menu**
+
+```
+Manage your saved configurations
+├─ Functions:
+│  • View current settings
+│  • Edit storage selections
+│  • Manage defaults location
+│  • See what's currently configured
+└─ Time: ~1 minute
+```
+
+**When to use**: You want to review or modify saved settings
+
+---
+
+## How to Save Defaults
+
+### Method 1: Save While Installing
+
+This is the easiest way:
+
+#### Step-by-Step: Create App Defaults
+
+```bash
+# 1. Run the installation script
+bash pihole-install.sh
+
+# 2. Choose installation mode
+#    ┌─────────────────────────┐
+#    │ Select installation mode:│
+#    │ 1) Default Settings     │
+#    │ 2) Advanced Settings    │
+#    │ 3) User Defaults        │
+#    │ 4) App Defaults         │
+#    │ 5) Settings Menu        │
+#    └─────────────────────────┘
+#
+#    Enter: 2 (Advanced Settings)
+
+# 3. Answer all configuration questions
+#    • Container name? → my-pihole
+#    • CPU cores? → 4
+#    • RAM amount? → 2048
+#    • Disk size? → 20
+#    • SSH access? → yes
+#    ... (more options)
+
+# 4. Review summary (shown before creation)
+#    ✓ Confirm to proceed
+
+# 5. After creation completes, you'll see:
+#    ┌──────────────────────────────────┐
+#    │ Save as App Defaults for PiHole? │
+#    │ (Yes/No)                         │
+#    └──────────────────────────────────┘
+#
+#    Select: Yes
+
+# 6. Done! Settings saved to:
+#    /usr/local/community-scripts/defaults/pihole.vars
+```
+
+#### Step-by-Step: Create User Defaults
+
+```bash
+# Same as App Defaults, but:
+# When you select "Advanced Settings"
+# FIRST app you run with this selection will offer
+# to save as "User Defaults" additionally
+
+# This saves to: /usr/local/community-scripts/default.vars
+```
+
+---
+
+### Method 2: Manual File Creation
+
+For advanced users who want to create defaults without running installation:
+
+```bash
+# Create User Defaults manually
+sudo tee /usr/local/community-scripts/default.vars > /dev/null << 'EOF'
+# Global User Defaults
+var_cpu=4
+var_ram=2048
+var_disk=20
+var_unprivileged=1
+var_brg=vmbr0
+var_gateway=192.168.1.1
+var_timezone=Europe/Berlin
+var_ssh=yes
+var_container_storage=local
+var_template_storage=local
+EOF
+
+# Create App Defaults manually
+sudo tee /usr/local/community-scripts/defaults/pihole.vars > /dev/null << 'EOF'
+# App-specific defaults for PiHole
+var_unprivileged=1
+var_cpu=2
+var_ram=1024
+var_disk=10
+var_brg=vmbr0
+var_gateway=192.168.1.1
+var_hostname=pihole
+var_container_storage=local
+var_template_storage=local
+EOF
+```
+
+---
+
+### Method 3: Using Environment Variables
+
+Set defaults via environment before running:
+
+```bash
+# Set as environment variables
+export var_cpu=4
+export var_ram=2048
+export var_disk=20
+export var_hostname=my-container
+
+# Run installation
+bash pihole-install.sh
+
+# These settings will be used
+# (Can still be overridden by saved defaults)
+```
+
+---
+
+## How to Use Saved Defaults
+
+### Using User Defaults
+
+```bash
+# 1. Run any installation script
+bash pihole-install.sh
+
+# 2. When asked for mode, select:
+#    Option: 3 (User Defaults)
+
+# 3. Your settings from default.vars are applied
+# 4. Container created with your saved settings
+```
+
+### Using App Defaults
+
+```bash
+# 1. Run the app you configured before
+bash pihole-install.sh
+
+# 2. When asked for mode, select:
+#    Option: 4 (App Defaults)
+
+# 3. Your settings from defaults/pihole.vars are applied
+# 4. Container created with exact same settings
+```
+
+### Overriding Saved Defaults
+
+```bash
+# Even if you have defaults saved,
+# you can override them with environment variables
+
+export var_cpu=8  # Override saved defaults
+export var_hostname=custom-name
+
+bash pihole-install.sh
+# Installation will use these values instead of saved defaults
+```
+
+---
+

+
+## Troubleshooting
+
+### "App Defaults not available" Message
+
+**Problem**: You want to use App Defaults, but option says they're not available
+
+**Solution**:
+1. You haven't created App Defaults yet for this app
+2. Run the app with "Advanced Settings"
+3. When finished, save as App Defaults
+4. Next time, App Defaults will be available
+
+---
+
+### "Settings not being applied"
+
+**Problem**: You saved defaults, but they're not being used
+
+**Checklist**:
+```bash
+# 1. Verify files exist
+ls -la /usr/local/community-scripts/default.vars
+ls -la /usr/local/community-scripts/defaults/<app>.vars
+
+# 2. Check file permissions (should be readable)
+stat /usr/local/community-scripts/default.vars
+
+# 3. Verify correct mode selected
+#    (Make sure you selected "User Defaults" or "App Defaults")
+
+# 4. Check for environment variable override
+env | grep var_
+#    If you have var_* set in environment,
+#    those override your saved defaults
+```
+
+---
+
+### "Cannot write to defaults location"
+
+**Problem**: Permission denied when saving defaults
+
+**Solution**:
+```bash
+# Create the defaults directory if missing
+sudo mkdir -p /usr/local/community-scripts/defaults
+
+# Fix permissions
+sudo chmod 755 /usr/local/community-scripts
+sudo chmod 755 /usr/local/community-scripts/defaults
+
+# Make sure you're running as root
+sudo bash pihole-install.sh
+```
+
+---
+
+### "Defaults directory doesn't exist"
+
+**Problem**: Script can't find where to save defaults
+
+**Solution**:
+```bash
+# Create the directory
+sudo mkdir -p /usr/local/community-scripts/defaults
+
+# Verify
+ls -la /usr/local/community-scripts/
+```
+
+---
+
+### Settings seem random or wrong
+
+**Problem**: Container gets different settings than expected
+
+**Possible Causes & Solutions**:
+
+```bash
+# 1. Check if environment variables are set
+env | grep var_
+# If you see var_* entries, those override your defaults
+# Clear them: unset var_cpu var_ram (etc)
+
+# 2. Verify correct defaults are in files
+cat /usr/local/community-scripts/default.vars
+cat /usr/local/community-scripts/defaults/pihole.vars
+
+# 3. Check which mode you actually selected
+# (Script output shows which defaults were applied)
+
+# 4. Check Proxmox logs for errors
+sudo journalctl -u pve-daemon -n 50
+```
+
+---
+
+### "Variable not recognized"
+
+**Problem**: You set a variable that doesn't work
+
+**Solution**:
+Only certain variables are allowed (security whitelist):
+
+```
+Allowed variables (starting with var_):
+✓ var_cpu, var_ram, var_disk, var_unprivileged
+✓ var_brg, var_gateway, var_mtu, var_vlan, var_net
+✓ var_hostname, var_pw, var_timezone
+✓ var_ssh, var_ssh_authorized_key
+✓ var_fuse, var_tun, var_nesting, var_keyctl
+✓ var_container_storage, var_template_storage
+✓ var_tags, var_verbose
+✓ var_apt_cacher, var_apt_cacher_ip
+✓ var_protection, var_mount_fs
+
+✗ Other variables are NOT supported
+```
+
+---
+
+## Best Practices
+
+### ✅ Do's
+
+✓ Use **App Defaults** when you want app-specific settings
+✓ Use **User Defaults** for your global preferences
+✓ Edit defaults files directly with `nano` (safe)
+✓ Keep separate App Defaults for each app
+✓ Back up your defaults regularly
+✓ Use environment variables for temporary overrides
+
+### ❌ Don'ts
+
+✗ Don't use `source` on defaults files (security risk)
+✗ Don't put sensitive passwords in defaults (use SSH keys)
+✗ Don't modify defaults while installation is running
+✗ Don't delete defaults.d while containers are being created
+✗ Don't use special characters without escaping
+
+---
+
+## Quick Reference

+# Comments start with #
+var_name=value
+
+# No spaces around =
+✓ var_cpu=4
+✗ var_cpu = 4
+
+# String values don't need quotes
+✓ var_hostname=mycontainer
+✓ var_hostname='mycontainer'

+var_hostname=myserver bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/debian.sh)"
+```
+
+### Complete Configuration Example
+
+```bash
+#!/bin/bash
+# deploy-single.sh - Deploy a single container with full configuration
+
+var_unprivileged=1 \
+var_cpu=4 \
+var_ram=4096 \
+var_disk=30 \
+var_hostname=production-app \
+var_brg=vmbr0 \
+var_net=dhcp \
+var_ipv6_method=none \
+var_ssh=yes \
+var_ssh_authorized_key="ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQ... admin@workstation" \
+var_nesting=1 \
+var_tags=production,automated \
+var_protection=yes \
+var_verbose=no \
+  bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVED/main/ct/debian.sh)"
+
+echo "✓ Container deployed successfully"
+```
+
+### Using App Defaults
+
+**Step 1: Create defaults once (interactive)**
+```bash
+bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVED/main/ct/pihole.sh)"
+# Select "Advanced Settings" → Configure → Save as "App Defaults"
+```
+
+**Step 2: Deploy unattended (uses saved defaults)**
+```bash
+#!/bin/bash
+# deploy-with-defaults.sh
+
+# App defaults are loaded automatically
+bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVED/main/ct/pihole.sh)"
+# Script will use /usr/local/community-scripts/defaults/pihole.vars
+```

+
+## Batch Deployments
+
+### Deploy Multiple Containers
+
+#### Simple Loop
+
+```bash
+#!/bin/bash
+# batch-deploy-simple.sh
+
+apps=("debian" "ubuntu" "alpine")
+
+for app in "${apps[@]}"; do

+
+  echo "✓ $app deployed"
+  sleep 5  # Wait between deployments
+done
+```
+
+#### Advanced with Configuration Array
+
+```bash

+#### Parallel Deployment
+
+```bash

+## Overview
+
+### Purpose
+
+Installation scripts (`install/AppName-install.sh`) **run inside the LXC container** and are responsible for:
+
+1. Setting up the container OS (updates, packages)
+2. Installing application dependencies
+3. Downloading and configuring the application
+4. Setting up services and systemd units
+5. Creating version tracking files for updates
+6. Generating credentials/configurations
+7. Final cleanup and validation
+
+### Execution Flow
+
+```
+ct/AppName.sh (Proxmox Host)
+       ↓
+build_container()
+       ↓
+pct exec CTID bash -c "$(cat install/AppName-install.sh)"
+       ↓
+install/AppName-install.sh (Inside Container)
+       ↓
+Container Ready with App Installed

+
+---
+
+## Best Practices
+
+### ✅ DO:
+
+1. **Always Use $STD for Commands**
+```bash
+# ✅ Good: Respects VERBOSE setting
+$STD apt-get install -y nginx
+```
+
+2. **Generate Random Passwords Safely**
+```bash
+# ✅ Good: Alphanumeric only
+DB_PASS=$(openssl rand -base64 18 | tr -dc 'a-zA-Z0-9' | head -c13)
+```
+
+3. **Check Command Success**
+```bash
+# ✅ Good: Verify success
+if ! wget -q "https://example.com/file.tar.gz"; then
+  msg_error "Download failed"
+  exit 1
+fi
+```
+
+4. **Set Proper Permissions**
+```bash
+# ✅ Good: Explicit permissions
+chown -R www-data:www-data /opt/appname
+chmod -R 755 /opt/appname
+```
+
+5. **Save Version for Update Checks**
+```bash
+# ✅ Good: Version tracked
+echo "${RELEASE}" > /opt/${APP}_version.txt
+```
+
+6. **Handle Alpine vs Debian Differences**
+```bash
+# ✅ Good: Detect OS
+if grep -qi 'alpine' /etc/os-release; then
+  apk add package
+else
+  apt-get install -y package
+fi
+```
+
+### ❌ DON'T:
+
+1. **Hardcode Versions**
+```bash
+# ❌ Bad: Won't auto-update
+wget https://example.com/app-1.2.3.tar.gz
+```
+
+2. **Use Root Without Password**
+```bash
+# ❌ Bad: Security risk
+mysql -u root
+```
+
+3. **Forget Error Handling**
+```bash
+# ❌ Bad: Silent failures
+wget https://example.com/file
+tar -xzf file
+```
+
+4. **Leave Temporary Files**
+```bash
+# ✅ Always cleanup
+rm -rf /opt/app-${RELEASE}.tar.gz
+```
+

+
+## Troubleshooting
+
+### Installation Hangs
+
+**Check internet connectivity**:
+```bash
+ping -c 1 8.8.8.8
+```
+
+**Enable verbose mode**:
+```bash
+# In ct/AppName.sh, before running
+VERBOSE="yes" bash install/AppName-install.sh
+```
+
+### Package Not Found
+
+**Update package lists**:
+```bash
+apt update
+apt-cache search package_name
+```
+
+### Service Won't Start
+
+**Check logs**:
+```bash
+journalctl -u appname -n 50
+systemctl status appname
+```

+- **Setup Alpine container** → [misc/alpine-install.func/](../misc/alpine-install.func/)
+- **Debug installation errors** → [EXIT_CODES.md](../EXIT_CODES.md)
+- **Use dev mode** → [DEV_MODE.md](../DEV_MODE.md)
+
+## Alpine vs Debian
+
+- **Debian-based** → Use `tools.func`, `install.func`, `systemctl`

+    ↓
+cleanup_lxc()                    ← Final cleanup

+```
+
+## Common Usage Patterns
+
+### Basic Alpine Setup
+```bash
+#!/usr/bin/env bash
+source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
+setting_up_container
+update_os
+
+# Install Alpine-specific packages
+apk add --no-cache curl wget git
+
+# ... application installation ...
+
+motd_ssh
+customize
+cleanup_lxc
+```
+
+### With IPv6 Enabled
+```bash
+#!/usr/bin/env bash
+source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
+setting_up_container
+verb_ip6
+update_os
+network_check
+
+# ... application installation ...
+
+motd_ssh
+customize
+cleanup_lxc
+```
+
+### Installing Services
+```bash
+#!/usr/bin/env bash
+source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
+setting_up_container
+update_os
+
+# Install via apk
+apk add --no-cache nginx
+
+# Enable and start service on Alpine
+rc-update add nginx
+rc-service nginx start
+
+motd_ssh
+customize
+cleanup_lxc
+```
+
+## Best Practices
+
+### ✅ DO
+- Use `apk add --no-cache` to reduce image size
+- Enable IPv6 if application needs it (`verb_ip6`)
+- Use `rc-service` for service management on Alpine
+- Check `/etc/network/interfaces` for IPv6 persistence
+- Test network connectivity before critical operations
+- Use `$STD` for output suppression in production
+
+### ❌ DON'T
+- Use `apt-get` commands (Alpine doesn't have apt)
+- Use `systemctl` (Alpine uses OpenRC, not systemd)
+- Use `service` command (it may not exist on Alpine)
+- Assume systemd exists on Alpine
+- Forget to add `--no-cache` flag to `apk add`
+- Hardcode paths from Debian (different on Alpine)
+
+## Alpine-Specific Considerations
+
+### Package Names
+Some packages have different names on Alpine:
+```bash
+# Debian        → Alpine
+# curl          → curl (same)
+# wget          → wget (same)
+# python3       → python3 (same)
+# libpq5        → postgresql-client
+# libmariadb3   → mariadb-client
+```
+
+### Service Management
+```bash
+# Debian (systemd)      → Alpine (OpenRC)
+systemctl start nginx   → rc-service nginx start
+systemctl enable nginx  → rc-update add nginx
+systemctl status nginx  → rc-service nginx status
+```
+
+### Network Configuration
+```bash
+# Debian (Netplan)                → Alpine (/etc/network/interfaces)
+/etc/netplan/01-*.yaml            → /etc/network/interfaces
+netplan apply                      → Configure directly in interfaces
+
+# Enable IPv6 persistently on Alpine:
+# Add to /etc/network/interfaces:
+# iface eth0 inet6 static
+#     address <IPv6_ADDRESS>
+```
+
+## Troubleshooting
+
+### "apk command not found"
+- This is Alpine Linux, not Debian
+- Install packages with `apk add` instead of `apt-get install`
+- Example: `apk add --no-cache curl wget`
+
+### "IPv6 not persisting after reboot"
+- IPv6 must be configured in `/etc/network/interfaces`
+- The `verb_ip6()` function handles this automatically
+- Verify: `cat /etc/network/interfaces`
+
+### "Service won't start on Alpine"
+- Alpine uses OpenRC, not systemd
+- Use `rc-service nginx start` instead of `systemctl start nginx`
+- Enable service: `rc-update add nginx`
+- Check logs: `/var/log/` or `rc-service nginx status`
+
+### "Container too large"
+- Alpine should be much smaller than Debian
+- Verify using `apk add --no-cache` (removes package cache)
+- Example: `apk add --no-cache nginx` (not `apk add nginx`)

+## Alpine vs Debian Package Differences
+
+| Package | Debian | Alpine |
+|---------|:---:|:---:|
+| nginx | `apt-get install nginx` | `apk add nginx` |
+| mariadb | `apt-get install mariadb-server` | `apk add mariadb` |
+| PostgreSQL | `apt-get install postgresql` | `apk add postgresql` |
+| Node.js | `apt-get install nodejs npm` | `apk add nodejs npm` |
+| Docker | Special setup | `apk add docker` |
+| Python | `apt-get install python3 python3-pip` | `apk add python3 py3-pip` |
+
+## Common Usage Patterns
+
+### Basic Alpine Tool Installation
+```bash
+#!/usr/bin/env bash
+source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
+
+# Update package lists
+apk_update
+
+# Install nginx
+apk_add nginx
+
+# Start service
+rc-service nginx start
+rc-update add nginx
+```
+
+### With Community Repository
+```bash
+#!/usr/bin/env bash
+source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
+
+# Enable community repo for more packages
+add_community_repo
+
+# Update and install
+apk_update
+apk_add postgresql postgresql-client
+
+# Start service
+rc-service postgresql start
+```
+
+### Development Environment
+```bash
+#!/usr/bin/env bash
+source /dev/stdin <<<"$FUNCTIONS_FILE_PATH"
+
+# Install build tools
+setup_build_tools
+setup_git
+setup_nodejs "20"
+
+# Install application
+git clone https://example.com/app
+cd app
+npm install
+```
+
+## Best Practices
+
+### ✅ DO
+- Always use `apk add --no-cache` to keep images small
+- Call `apk_update()` before installing packages
+- Use community repository for more packages (`add_community_repo`)
+- Handle apk locks gracefully with retry logic
+- Use `$STD` variable for output control
+- Check if tool already installed before reinstalling
+
+### ❌ DON'T
+- Use `apt-get` commands (Alpine doesn't have apt)
+- Install packages without `--no-cache` flag
+- Hardcode Alpine-specific paths
+- Mix Alpine and Debian commands
+- Forget to enable services with `rc-update`
+- Use `systemctl` (Alpine has OpenRC, not systemd)
+
+## Alpine Repository Configuration
+
+### Default Repositories
+Alpine comes with main repository enabled by default. Additional repos:
+
+```bash
+# Community repository (apk add php, go, rust, etc.)
+add_community_repo
+
+# Testing repository (bleeding edge packages)
+add_testing_repo
+```
+
+### Repository Locations
+```bash
+/etc/apk/repositories      # Main repo list
+/etc/apk/keys/             # GPG keys for repos
+/var/cache/apk/            # Package cache
+```
+
+## Package Size Optimization
+
+Alpine is designed for small container images:
+
+```bash
+# DON'T: Leaves package cache (increases image size)
+apk add nginx
+
+# DO: Remove cache to reduce size
+apk add --no-cache nginx
+
+# Expected sizes:
+# Alpine base: ~5MB
+# Alpine + nginx: ~10-15MB
+# Debian base: ~75MB
+# Debian + nginx: ~90-95MB
+```
+
+## Service Management on Alpine
+
+### Using OpenRC
+```bash
+# Start service immediately
+rc-service nginx start
+
+# Stop service
+rc-service nginx stop
+
+# Restart service
+rc-service nginx restart
+
+# Enable at boot
+rc-update add nginx
+
+# Disable at boot
+rc-update del nginx
+
+# List enabled services
+rc-update show
+```
+
+## Troubleshooting
+
+### "apk: lock is held by PID"
+```bash
+# Alpine apk database is locked (another process using apk)
+# Wait a moment
+sleep 5
+apk_update
+
+# Or manually:
+rm /var/lib/apk/lock 2>/dev/null || true
+apk update
+```
+
+### "Package not found"
+```bash
+# May be in community or testing repository
+add_community_repo
+apk_update
+apk_add package-name
+```
+
+### "Repository not responding"
+```bash
+# Alpine repo may be slow or unreachable
+# Try updating again with retry logic
+apk_update  # Built-in retry logic
+
+# Or manually retry
+sleep 10
+apk update
+```
+
+### "Service fails to start"
+```bash
+# Check service status on Alpine
+rc-service nginx status
+
+# View logs
+tail /var/log/nginx/error.log
+
+# Verify configuration
+nginx -t
+```
