I'm going to contradict myself and point out that mount with label or UUID is made unambiguous via either the default subvolume being mounted, or the -o subvol= option being specified. The volume label and UUID doesn't apply to umount because it's an ambiguous command. You'd have to umount a mountpoint, or possibly a subvolume specific UUID. Chris Murphy
