AIUI there is/was a long-term plan to integrate this as core

first place. I believe those involved didn't think the LVM-based
implementation was clean/robust enough to use by default, but a
btrfs-based implementation would be. Do correct me if I'm wrong.
I don't think snapshots are a partcularly good solution, unless there's
some way to only roll back the rpm/yum transaction without also rolling
back unrelated changes.
