Lorax successfully builds complete Fedora installation media + - Supports both x86_64 and aarch64 architectures + - Handles package resolution, dependency management automatically + - Generates bootloader configuration for UEFI systems + +2. **Build Process**: + - Downloads packages from Fedora repositories (releases + updates) + - Installs 874 packages for installation environment + - Creates compressed filesystem images + - Generates bootable ISO with UEFI support + - Total build time: ~7 minutes + +3. **Docker Requirements**: + - Privileged mode required for lorax operations + - Sufficient disk space needed (~2GB for output) + - Volume mounts must allow lorax to create directories + - SELinux can be disabled in container + +4. **Output Artifacts**: + - boot.iso: Main bootable installation media + - efiboot.img: EFI boot partition image + - install.img: Installation root filesystem + -
