Some time back there was discussion of being able to rollback yum
btrfs snapshotting. As I recall, it turned out that the default btrfs install
was not setup correctly to make this feasible (I had briefly tested it on my
machine). I haven't heard anything since - this seems like a great idea.
Well, yum is being retired in favor of dnf and btrfs still isn't the
default filesystem because it still isn't stable enough. So that's
basically what happened.
Now, it is possible to do this in dnf (either with btrfs or with dm
snapshots) but I'm not aware of anyone working on it. Fedora has the
Snapper tool available in the repos, which could do snapshotting
outside of dnf as well.
