-> The idea is that if an update goes wrong and something stops working, then you can just reboot and revert back to an older snapshot in which everything worked.
-->As seen in Solaris and beadm.
beadm and ZFS = fantastic.
Or for time being, duplicate Solaris 10 Live Upgrade ability (non-ZFS filesystems). Gosh I loved that ability. Wish the Linux camps would either do a ZFS shoe-in compatible (done legally somehow) or provide a Live Upgrade ability to flip-flop between boot environments.
