How Our Mainframe-Focused Working Group Solved Our Linux Distribution Maintaine...
summary
A Linux distributions working group started in 2021 combines s390x maintainers from openSUSE, Debian, Fedora, Rocky and Alma to share hardware, CI and fixes. The group supplies VMs and CI pointers (Ubuntu build servers, openSUSE OBS, self‑hosted runners), holds monthly meetings, and turns up quick wins like fixed xrdp client build in five minutes and distributed VMs for Alpine and maintainers recruited while expanded openQA to Rocky and Alma Linux so builds stop blocking releases.
