It's a very broad rollback implementation. I think an eventual goal for the yum
plugin, once btrfs is stable, is to make it more flexible. Maybe where /home is exempt
from rollback.
It's already usable with LVM and BtrFS, and you can exclude arbitrary
mount points.
However creating mount points in a way that makes it only "rollback"
those things you want is ... non-trivial.
