I believe that btrfs and ZFS both implement snapshotting, but they're
not easy choices to recommend to Thomas.  Btrfs is still very "beta"
in many ways, although it's starting to get traction in production
according to some things I've see on the 'net.  I don't know if the
problems reported (replication etc) would affect Thomas.  ZFS requires
building your own kernel because of licensing issues I believe.

Maybe there are other standard Linux FSes he could use that provide
snapshotting natively?

LVM seems like overkill and adds administrative burden just to get

I don't think Thomas will be messing with /boot, and he hasn't
mentioned ever having a system that can't boot to the point where init
starts, so this probably isn't a problem for him.
