LVM snapshots (with a filesystem ontop) can be used to take a snap-
shot which can later either be removed (if the intended change/upgrade
worked well) or can be used to roll the system back to the state where
the snapshot was taken.

This is a bit complicated though because /boot has still to live on
a partition (not LVM volume), and has to be taken care of.
