#!/bin/bash
#
# Build Archipelago Auto-Installer ISO (StartOS-like)
# 
# This creates an ISO that automatically installs to the internal disk
# with minimal user interaction - similar to StartOS experience.
#
# CRITICAL: This script CAPTURES the LIVE SERVER state by default.
# Set DEV_SERVER to point to your development server.
#
# Usage: 
#   DEV_SERVER=archipelago@192.168.1.228 ./build-auto-installer-iso.sh
#   OR just: ./build-auto-installer-iso.sh (uses default server)
#
# To build from source instead:
#   BUILD_FROM_SOURCE=1 ./build-auto-installer-iso.sh
#
# Features:
# - Pre-built root filesystem (no network needed during install)
# - Auto-detects internal disk (skips USB boot drive)
# - Automatic installation with progress display
# - Boots directly to web UI after install
#
# Image versions: sourced from scripts/image-versions.sh (single source of truth).
# All container image references MUST use the $*_IMAGE variables defined there.
#
# --- PLANNED REFACTOR (post-beta) ---
# This script is ~1870 lines and should be split into a modular library.
# Proposed structure:
#   image-recipe/
#     build-auto-installer-iso.sh   — Main orchestrator (config, CLI args, step sequencing)
#     lib/
#       rootfs.sh                   — Step 1: Build root filesystem via Docker (~185 lines)
#       installer-env.sh            — Step 2: Download/extract Debian Live base ISO (~80 lines)
#       components.sh               — Step 3: Add Archipelago components (binary, configs, web UI) (~120 lines)
#       container-images.sh         — Step 3b: Bundle container images for offline install (~330 lines)
#       auto-install-script.sh      — Step 4: Generate the embedded auto-install.sh (~615 lines)
#       boot-config.sh              — Step 5: Configure live boot auto-start + overlay squashfs (~215 lines)
#       create-iso.sh               — Step 6: Build final bootable ISO with xorriso/grub (~140 lines)
# Each lib/ script exports functions; main script sources them and calls in sequence.
# DO NOT split until tested on the build server — this is critical infrastructure.
