I think the most practical thing is to build version N of self-hosting systems using version N-1 (in addition to supporting building N with N). If you are using the latest to build the latest, you can more easily get into unstable states.
For example, if a new version of the Fedora kernel broke virtio-net, and you immediately upgrade the build VMs, then the system falls apart and requires manual system administrator intervention - you can't build a new fixed kernel. Presumably version N-1 is more stable, although this is somewhat obviated by the Fedora kernel maintenance model of keeping all branches in sync. -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
