Jul 1, 2026

July 2026 monthly summary for rhinstaller/anaconda: Delivered a focused fix to systemd unit handling during kickstart provisioning. The is_service_installed function now recognizes all standard systemd unit suffixes and applies .service only to bare names, enabling management of socket and other units via kickstart. This eliminates false 'missing' checks (e.g., cockpit.socket) and improves automation reliability for RHEL-based deployments. Commit f0d6ad4f539babfe3ccc67d8a3d6b6554097191e. Related: RHEL-178289. Business impact: reduced install-time failures, fewer manual remediations, and more consistent automated deployments. Skills demonstrated: Python code adjustments, understanding of systemd unit naming, and kickstart integration.

February 2026: Delivered concise, business-focused features and reliability improvements across rhinstaller/anaconda and cockpit-project/bots, prioritizing installer robustness, CI/CD modernization, and Fedora release readiness. In rhinstaller/anaconda, installer robustness and security policy handling were enhanced with a single-instance launcher to prevent duplicate installs, robust timeout callback handling, and automatic SELinux policy reload after exit to ensure correct security contexts post-install. Notable commits include liveinst single-instance lock (7fa940a638e6e635097251a4f779820327f6841c), GLib timeout callback fix (ac1c9ee7839c4d31805519e4a2898196c2613e69), and policy reload at exit (2a35197f8518ca99031b77bfe2a9e3c97e74be83). CI/CD infrastructure and configuration improvements strengthened the build and release pipeline: switching try-release-daily to public runners, updating Fedora targets to 44, enabling manual container-rebuild-action trigger, and aligning container and release workflows (commits d36f217a3c6643551609336c711dd8c891913ffb, e9fc395bdb8b33a56003a0975c061520f803f4f7, 9ac06cfcbf26c5f122e71d1b6ce0c00160b860f0, 657a9bf73cf5eb88b75acdf61a8bc556e7b07d2e, 510288d0ea1b097eecfcd30f6d966f603e0d4f70). Changelog and packaging enhancements improve traceability and install reliability: extracting Red Hat Bugzilla references for non-RHEL branches (035423960747717d1c2167627c155867a48a2d35) and adding python3-crypt-r dependency to ELN installer (8d85c237e6a1cf3ec0c7d42dfd5d880d2c16206c). Tests were strengthened with a password hash validation fix (cfd33a6db87ac6d6e262b4bebe82f28bda5bc1ab). In cockpit-project/bots, Fedora 44 WebUI images and boot scripts were added to support the latest Fedora release (abcd69c9cd7ae722d2b2b21ea65b279752e84dde). Overall impact: higher installer reliability, faster and more transparent releases, expanded Fedora support, and improved security posture. Demonstrated skills: Python/GLib integration, SELinux policy management, CI/CD automation, container workflows, packaging and test automation, and WebUI provisioning.
