In my opinion, if we really want to speak about a way to implement that
kind of snapshoting, we should start thinking about providing a better
integration with lvm, from the root. lvm can take care of the snapshots on
a non-expensive way, and it would be relatively easy to implement. However
a lot of stuff would need to be re-documented, starting from the handbook,
and the init system.

Into my eyes, it's the only serious way to do this at least until btrfs is
ready for the masses, and there's a long way until we reach that point
still.

As for the package bits, it's true that the semantic and delimitation
about what's part of the system and what isn't, and the mechanism to handle
some things could be better, but I've grown accustomed to the way it is and
I really don't care if that changes or not.
