June 2025: Delivered substantial distro-management enhancements across major/images and osbuild/osbuild, driving portability, maintainability, and automation readiness. Features include Fedora-specific match tightening with RHEL generalization, YAML-driven image configuration for RHEL8/RHEL9, and new distro matching concepts (distro_like) with DNFConfig and consistent Product() usage. We also completed a cleanup of obsolete directories, standardized naming (ImgTypeLabel -> ISOLabel), and improved manifest tooling and documentation. In parallel, targeted bug fixes and tests improved reliability of inline sources and QEMU logging, strengthening CI pipelines and vendor interoperability.

March 2025 monthly summary for development work across major/images and osbuild/osbuild. Focused on stabilizing distro-driven packaging, enabling YAML-driven distro configurations, and tightening testing/CI. Key improvements shipped across two repos include: (1) Distro/Packaging overhaul: migrated to packagesets.Load() for RHEL, introduced distro_name condition, experimental yamldir support and loader/interface improvements; enhanced yamlloader to handle diverse dir layouts; added logging when experimental overrideDir is used; extracted RHEL7 package sets to a single YAML; fixed hardcoded packagesets in RHEL9; README updated. (2) API stability and cleanup: refactored packageSetFunc() to return errors; added common.Must() helper; removed unused manifest.Arch; renamed packagesets.Load to defs.PackageSet and updated distro.yaml naming. (3) Gen-manifests improvements: de-duplicated packages at the depsolve level; added notes about limits of gen-manifests-diff; documented the workflow and usage. (4) Bootstrap and manifest enhancements: added bootstrap support to buildroots, exposed UseBootstrapContainer option, and introduced bootstrap-related pipelines; included integration test for UseBootstrapContainer. (5) Testing and tooling enhancements: introduced tests for grub-mkimage argument handling and RPM boot_root schema validation; added util.experimentalflags helpers with unit tests; workflows tweaked for CI hygiene.”,
