The concept is simple enough - create a snapshot before doing anything hazardous, and provide a mechanism for mounting a specific snapshot at boot time. Here's a link to the Fedora proposal... https://fedoraproject.org/wiki/Features/SystemRollbackWithBtrfs It seems this feature is partially implemented in F13 - the automatic snapshots are enabled, though the UI is missing. On an LFS, there's no automatic update process, so I figure I'd just create periodic snapshots, say a weekly cron job, or maybe just manually. And then configure an entry in grub to boot from the previous snapshot. The concept is simple enough, I just haven't had a good chance to try it out... Simon.
