Sounds cool.. although if you're going to the bother of having separate /
and /home, you might want to have separate spindles (disks) for system speed.
Things like firefox and openoffice can slew the heads a bit (if system speed
really is your goal here).

If this is your goal (assume you're talking about using snapshots) then look
into using XFS so that you have a filesystem that you can sync and lock while
doing your partition snap.
