ubiquity/apt-clone should duplicate the btrfs snapshot magic found in update-manager

[Evan]

Binary package hint: ubiquity

aquarius: the idea is really to make upgrades totally painless, in that if they fail halfway, or break somehow, or you just plain don't like the upgrade, you can just say "no problem" and go back to what you had before which is totally unbroken. It's a psychological safety net, and it also means that upgrades could be more aggressive about fixing stuff because if it doesn't work it doesn't torch your machine
ev: yeah, update-manager/apt already has this for the btrfs case, though you've reminded me that the installer should do it as well for the upgrade option

This should be relatively straightforaward with the apt_btrfs_snapshot python module. On the livecd it may actually be a little bit more complicated because "/" is not the btrfs and /etc/fstab is not the "real" one.
