Monthly summary for 2025-12 (rhinstaller/anaconda): Deliverables focused on improving network persistence, installer behavior, and cross-distro policy applicability. Implemented Network Initramfs Persistence and Default Profile Control by introducing PersistInitramfsConfiguration and removing DumpMissingConfigFiles, ensuring only installation-bound connections are persisted and preserved for GUI-driven profile creation. Stopped automatic creation of default wired profiles during installation to prevent pre-named autoconnections, aligning installed system state with user-configured profiles. Added Fedora ELN variant handling to the RHEL autoconnections policy to ensure correct policy application across distributions (INSTALLER-4534). Published release notes documenting the INSTALLER-3088 changes. Overall impact: reduced misconfigurations, streamlined installer flow, and improved reliability for enterprise deployments with consistent network behavior across platforms.

July 2025 monthly summary for rhinstaller/anaconda focusing on test reliability improvements. Implemented unit test isolation by mocking the rsync command and related execution paths in the testing environment, enabling tests to run without a functional rsync install. This reduces test flakiness, shortens CI feedback loops, and strengthens confidence in changes affecting rsync-related logic. The work aligns with the repo’s quality goals and lowers maintenance costs by decoupling tests from external tooling. Relevant commit provides a deterministic test surface for rsync-dependent code.

April 2025 – rhinstaller/anaconda: Enhanced EFI partition handling in the storage/partition-detection workflow. Implemented a fix that correctly detects and includes EFI partitions linked to Windows and macOS installations, including scenarios with multiple EFI partitions. The algorithm now prioritizes partitions on disks already hosting other OS partitions, improving overall system detection accuracy and reducing install-time mis-detections in multi-boot environments. This change is backed by the commit 9a8291095759fa9d3f30150e0b9c2c74da795a17 (storage: Fix EFI partition detection for other OSes).
