yeah ... someone or something completely botched that page, to where it neither reflect the original design goals nor improves upon them. far too much noise and pointlessness (like outbound links to FHS ... who the @#$% cares?!) in short, you need something like this in fstab or equiv: /dev/disk/by-label/btrfs-root /var/lib/btrfs-root btrfs defaults,noatime,subvolid=0 0 0 ... you need to mount `subvolid=0` or `subvolid=5` (same thing) somewhere, and make snapshots from there. subvolid 5 (for which 0 is an alias) is hard-coded to the top-level root. maybe try this: https://wiki.archlinux.org/index.php?title=Installing_on_Btrfs_root&oldid=185175 -- C Anthony
