Background story : for some SIGs building for/against 8-stream (and hopefully soon for/against 9-stream), we'd like to upgrade cbs.centos.org to koji 1.23 and all components on CentOS 8-stream.
The current setup is based on koji 1.19 on top of CentOS 7 nodes. While we have tested that it works fine for all builds and signing with 8-straem (tracking ticket https://pagure.io/centos-infra/issue/233) we have though a "small" issue that we'd like to announce first here : 8-stream doesn't exist for the following architectures : ppc64 (Big Endian, while ppc64le - Little Endian - exists) and armhfp.
I had a quick survey on what is being built/maintained (and so pushed out to mirror CDN) and ppc64/armhfp aren't even used. So it seems that removing ppc64/armhfp support from CBS is the way to go and it wouldn't hurt any SIG.
The only SIG that actually builds and ships packages to external mirror is the Infra SIG (so "us"), but we're building pkgs just because we had to maintain that arch ourselves, meaning that if we remove it from cbs, we don't have to maintain infra for ppc64 anymore (for SIG, as pkgs from CentOS 7 distro itself will continue to be built and shipped, but they aren't built on cbs anyway)
Opinions ? thoughts ?
Depending on feedback (or lack of in this case), I'll announce the maintenance window about cbs.centos.org migration to 8-stream in the next days (normally planned for next week but waiting for some feedback)
Kind Regards,
