You can already mount a specific snapshot, so recovering from a broken update 
where you take a snapshot first is trivial.

The example does rollback of package updates too, but that somewhat glosses 
over some of the tricky corner cases.  Rolling back the files is easy, but 
you have to be aware of all of the applications running on the files you're 
replacing and restart them.
