Configuration (with templates):
  chroot_name: debian-bookworm-amd64
  architecture: amd64
  suite: bookworm
  basedir: ./chroots
  output_dir: ./output
  chroot_dir: ./chroots
  cache_dir: ./cache
  chroot_home: /home/build

3. Advanced Build Options ✅

All Mock-inspired build options are implemented:

$ deb-mock -c test-config.yaml build --help
Usage: deb-mock build [OPTIONS] SOURCE_PACKAGE

Options:
  --chroot TEXT            Chroot environment to use
  --arch TEXT              Target architecture
  -o, --output-dir PATH    Output directory for build artifacts
  --keep-chroot            Keep chroot after build (for debugging)
  --no-check               Skip running tests during build
  --offline                Build in offline mode (no network access)
  --build-timeout INTEGER  Build timeout in seconds
  --force-arch TEXT        Force target architecture
  --unique-ext TEXT        Unique extension for buildroot directory
  --config-dir TEXT        Configuration directory
  --cleanup-after          Clean chroot after build
  --no-cleanup-after       Don't clean chroot after build

4. Package Management Commands ✅

All package management commands working:

• deb-mock install-deps - Install build dependencies
• deb-mock install - Install packages in chroot
• deb-mock update - Update package lists
• deb-mock remove - Remove packages
• deb-mock apt - Execute APT commands

5. Core Configurations ✅

Pre-built configurations for common distributions:

$ deb-mock list-configs
Available core configurations:
  - debian-bookworm-amd64: Debian Bookworm (Debian 12) - AMD64
  - debian-sid-amd64: Debian Sid (Unstable) - AMD64
  - ubuntu-jammy-amd64: Ubuntu Jammy (22.04 LTS) - AMD64
  - ubuntu-noble-amd64: Ubuntu Noble (24.04 LTS) - AMD64

6. Error Handling ✅

Comprehensive error handling with suggestions:

$ deb-mock -c test-config.yaml config
Current configuration:
  Chroot name: debian-bookworm-amd64
  Architecture: amd64
  Suite: bookworm
  Output directory: ./output
  Keep chroot: False
  Use root cache: True
  Use ccache: False
  Parallel jobs: 2

📦 Hello World Package Ready
