Nov 1, 2025

Month 2025-11: Focused on strengthening test coverage for mdraid initialization after kernel upgrades in the cockpit-project/bots repository. Delivered a regression test ensuring mdraid sysfs initializes and reports state 'Running' after a kernel upgrade (RHEL 9.8), addressing a previously observed regression and improving upgrade reliability. Impact: Reduces production risk by catching regression early, improves deployment confidence in upgrade paths, and supports faster release readiness through automated verification of critical RAID initialization behavior.

Monthly summary for 2025-10 focusing on the Cockpit Bots repository. This period delivered cross-distro image improvements, reliability fixes, and enhanced debugging capabilities, aligning build artifacts with up-to-date baselines across CentOS, RHEL, Arch, Debian/Ubuntu, and Fedora CoreOS. The work emphasizes business value through more reliable images, streamlined builds, and improved observability. Key highlights include the following delivered changes and associated commits: - CentOS 10 DNS resolution fix (bug): Removed a systemd-resolved workaround after upstream fixes, reducing fragility in CentOS 10 images. Commit: 2ba3d67df5c550b29c393c091a76f2e5be3e78e7. - RHEL qemu-kvm block driver support (feature): Ensure the qemu-kvm-block-curl driver is installed on RHEL by re-adding the package dependency in the RHEL setup script. Commit: ced06526937fa4ea774b5b8042df4491dcfcbd02. - Arch Linux image cleanup and optimization (feature): Explicitly install test and cockpit dependencies, remove cloud-init and related deps, drop unused VCS and nginx, and simplify build dependencies by removing accountsservice. Commits: 9c526dd4b61716ca3e5e6d4810dc954fde3d8131; 28bfecede9a9467bc1d7c15726c553923d9e40b9; aec31258588d89f14e86cfa42a546fa23ca8cee3. - Diagnostics: installer crash logging and vendor data debugging (feature): Add logs for ipa-install crash scenarios on debian-testing and include vendor/model traceback data for Ubuntu-stable to aid debugging. Commits: 33f9daea09d8641b00ced65294591cfccb7dcaad; 931300d76cf6acebed9c8e30642996b4bd757a83. - Fedora CoreOS test mapping update (feature): Update the Fedora CoreOS base image version in the test mapping to Fedora 43. Commit: 13046607c0aa3fd568452da840eaff92b8d148a0. Overall impact and business value: - Increased reliability and consistency of images across major distros, reducing DNS startup failures, and ensuring required virtualization drivers are present on RHEL, enabling smoother deployment workflows. - Reduced image size and maintenance overhead on Arch Linux by pruning unnecessary packages and clarifying dependencies, accelerating CI/build times. - Improved observability and debugging capabilities, leading to faster issue diagnosis in installers across Debian/Ubuntu environments and better vendor data handling in image discovery. - Kept baseline testing aligned with current OS releases (Fedora CoreOS 43), supporting up-to-date validation of image configurations. Technologies and skills demonstrated: - Linux image provisioning and packaging strategies across CentOS, RHEL, Arch, Debian/Ubuntu, and Fedora CoreOS. - Build automation and dependency management (package manifests, setup scripts). - Observability enhancements (crash logging, vendor data debugging) and root-cause tracing in multi-distro contexts. - Cross-distro orchestration and CI integration considerations for ongoing reliability improvements.
