Yoni Selkowitz enhanced build reliability and cross-platform compatibility across several open source projects, including ofiwg/libfabric, 389ds/389-ds-base, rhinstaller/anaconda, teemtee/tmt, osbuild/image-builder-frontend, and osbuild/osbuild-composer. He addressed GCC 15 and C23 compatibility in C for libfabric, stabilized bundled database packaging in 389-ds-base using autoconf and automake, and enabled conditional live builds for ELN in anaconda through specfile logic. Yoni expanded Fedora ELN container support in tmt with shell scripting and containerization, improved Node.js packaging for Fedora 44, and maintained DNF dependency compatibility for osbuild-composer, demonstrating depth in build systems, packaging, and test automation.
March 2026 (osbuild/osbuild-composer) - Stabilized the Fedora/RHEL test environment by updating the DNF dependency to maintain compatibility with newer OS versions and by aligning test logic with the current dnf copr usage. Implemented in commit f1b4e40a36804eb8fd471873424ceba27d40fd13. Impact: improves CI reliability across Fedora/RHEL targets, reduces risk of version-specific test failures, and preserves coverage for upcoming releases.

February 2026: Osbuild Image Builder Frontend monthly summary focusing on packaging robustness and cross-SOA compatibility. Implemented Fedora 44 packaging compatibility for Node.js BuildRequires, aligning with Fedora 44 changes and ensuring compatibility with both legacy and updated packaging schemes. This prevents build-time failures and stabilizes image builds on Fedora 44. No new user-facing features were released this month; the work prioritized maintainability, alignment with upstream packaging standards, and reducing future migration risk.

Month: 2025-09 — rhinstaller/anaconda Key features delivered: - Conditional Live Build Support for ELN: Enabled the 'live' build option conditionally for ELN (Enterprise Linux Next) and related packages, allowing live subpackage builds for ELN Alternative Images without impacting RHEL builds by adjusting build conditions based on variables. (Commit: 58e7f4ce91e2144729f29e8ad2b5aa2199f858c3) Major bugs fixed: - No major bugs fixed this month. Focus was on feature enablement and ensuring build isolation between ELN and RHEL. Overall impact and accomplishments: - Enables ELN Alternative Image workflows without compromising RHEL stability, supporting ELN/EPEL planning and alignment with the CentOS Alternative Images SIG. - Demonstrates disciplined repo coordination, build-system conditioning, and forward-looking support for ELN live images. Technologies/skills demonstrated: - Build-condition engineering in the spec, variable-driven decision logic, cross-repo coordination, and awareness of ELN/EPEL roadmaps.
