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.
Sure.
For example, the builders should stay Fedora 19 until Fedora 20 is
officially released, then we will switch them to 20, etc.
Presumably version N-1 is more stable, although this is somewhat
obviated by the Fedora kernel maintenance model of keeping all
branches in sync.
We intend to re-install builders as needed, not during freezes and
probably in a rolling manner. So any breakage should be isolated to non
freeze windows.
