## Prerequisites and System Requirements

### Host System Requirements
- **OS**: Linux distribution with recent kernel (5.10+)
- **Architecture**: x86_64 (primary), other architectures supported
- **RAM**: Minimum 8GB, recommended 16GB+
- **Storage**: Minimum 50GB free space, recommended 100GB+
- **Network**: Internet access for package downloads and image pulls

### Required Software
```bash
# Core build tools
sudo apt update
sudo apt install -y \
    build-essential \
    git \
    curl \
    wget \
    python3 \
    python3-pip \

    just \
    podman \
    qemu-system-x86 \
    virt-manager \
    libvirt-daemon-system

# Python dependencies
pip3 install pyyaml jinja2

# Verify installations
just --version
podman --version
qemu-system-x86 --version
```

### Development Environment
```bash
# Create project directory
mkdir -p ~/debian-atomic
cd ~/debian-atomic

# Clone or initialize git repository
git init
git remote add origin https://git.raines.xyz/particle-os/debian-atomic.git
```

## Project Setup and Structure

### Directory Structure Creation
```bash
# Create project structure
mkdir -p {variants,treefiles,scripts,docs,reports,deb_packages}

# Create variant directories
mkdir -p variants/{base,workstation,server,testing,debian-bootc-base}

# Create treefile configurations
mkdir -p treefiles/{base,workstation,server,base-forky}

# Create documentation
mkdir -p docs/{deployment,troubleshooting,architecture}
```

### Initial Configuration Files
```bash
# Create .gitignore
cat > .gitignore << 'EOF'
# Build artifacts
*.qcow2
*.iso
*.img
build/
output/

# Temporary files
*.tmp
*.log
*.cache

# Package files
*.deb
*.rpm

# OSTree repositories

# Debian Atomic

A 1:1 parallel to Fedora Atomic for the Debian ecosystem.

## Quick Start

```bash
# Build base image
just compose-base

# Build workstation variant
just compose-workstation

# Test in VM
just test-variant workstation
```

## Architecture

- **Base**: Minimal Debian system with bootc
- **Workstation**: GNOME desktop variant
- **Server**: Minimal server CLI variant
- **Testing**: Core component testing variant

## Documentation

See `docs/` directory for detailed implementation guides.

## Core Component Preparation

### bootc Package Compilation
```bash
# Clone bootc source
cd ~/debian-atomic
git clone https://git.raines.xyz/particle-os/bootc.git
cd bootc

# Install build dependencies
sudo apt install -y \
    cargo \
    rustc \
    libssl-dev \
    pkg-config \
    libsystemd-dev \
    libostree-dev

# Build bootc
cargo build --release

# Create Debian package structure
mkdir -p debian/DEBIAN
mkdir -p debian/usr/bin
mkdir -p debian/usr/share/doc/bootc

# Copy binary
cp target/release/bootc debian/usr/bin/

# Create package metadata
cat > debian/DEBIAN/control << 'EOF'
Package: bootc
Version: 1.6.0-1~trixie1
Section: admin
Priority: optional
Architecture: amd64
Depends: libc6, libsystemd0, libostree-1-1
Description: Bootable Container Image Manager
 Bootc is a tool for managing bootable container images
 and converting them to bootable disk images.

# Build package
dpkg-deb --build debian
mv debian.deb ../deb_packages/bootc_1.6.0-1~trixie1_amd64.deb

cd ..
```

### apt-ostree Package Download
```bash
# Download latest apt-ostree package from CI
cd ~/debian-atomic/deb_packages

# Get latest build number from CI
wget "https://git.raines.xyz/particle-os/-/packages/debian/apt-ostree/latest/files" -O apt-ostree_latest.deb

# Download bootupd package

#!/bin/bash

# Install bootc-image-builder on Debian system
# This script installs the tool needed for Stage 2 of the deployment workflow

## Troubleshooting Guide

### Common Issues and Solutions

# Create troubleshooting guide
cat > docs/troubleshooting/common-issues.md << 'EOF'
# Common Issues and Solutions

## Build Issues

### 1. Package Not Found
**Problem**: `E: Package 'package-name' has no installation candidate`
**Solution**: Check package availability in Debian repositories
```bash
apt-cache search package-name
```

### 2. OSTree Repository Issues
**Problem**: `ostree: command not found`
**Solution**: Install OSTree package
```bash
sudo apt install ostree
```

### 3. Container Build Failures
**Problem**: Build fails with permission errors
**Solution**: Ensure podman is properly configured
```bash
podman system reset
podman system prune -a
```

## Runtime Issues

### 1. bootc install Failures
**Problem**: "No commit objects found" error
**Solution**: Use bootc-image-builder workflow instead of direct bootc install
```bash
# Correct approach:
sudo podman run --rm -it --privileged \
    --security-opt label=type:unconfined_t \
    -v ./output:/output \
    -v /var/lib/containers/storage:/var/lib/containers/storage \
    quay.io/centos-bootc/bootc-image-builder:latest \
    --type qcow2 your-image:latest
```

### 2. OSTree Repository Location Mismatch
**Problem**: Repository not found in expected location
**Solution**: Check actual repository location
```bash
find / -name "repo" -type d 2>/dev/null | grep ostree
```

### 3. Component Integration Failures
**Problem**: apt-ostree or bootupd not working
**Solution**: Verify package installation and dependencies
```bash
dpkg -l | grep -E "(apt-ostree|bootupd)"
```

## Performance Issues

### 1. Slow Build Times
**Problem**: Container builds taking too long
**Solution**: Use apt-cacher-ng for package caching
```bash
# Install apt-cacher-ng
sudo apt install apt-cacher-ng

# Configure apt to use proxy
echo 'Acquire::http::Proxy "http://localhost:3142";' | sudo tee /etc/apt/apt.conf.d/01proxy
```

### 2. High Memory Usage
**Problem**: Builds consuming too much memory
**Solution**: Limit podman resources
```bash
# Set memory limit
podman run --memory=4g your-image
```

## Network Issues

### 1. Package Download Failures
**Problem**: Cannot download packages during build
**Solution**: Check network connectivity and proxy settings
```bash
# Test connectivity
curl -I http://deb.debian.org/debian

# Check proxy settings
env | grep -i proxy
```

### 2. Image Pull Failures
**Problem**: Cannot pull container images
**Solution**: Verify registry access and authentication
```bash
# Test registry access
podman pull hello-world

# Check authentication
podman login your-registry.com
```

```
