# 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

    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.

# 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

sudo apt install ostree

3. Container Build Failures

Problem: Build fails with permission errors Solution: Ensure podman is properly configured

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

# 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

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

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

# 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

# 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

# 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

# Test registry access
podman pull hello-world

# Check authentication
podman login your-registry.com
