It does not work any more :-(

mount looks into /dev/partition to find the names of the
devices to scan. Unfortunately the LV names listed here can't
be found under /dev, as they are simply enumerated like "dm-12".

On the other hand: once you have LVM, you don't need no disk
labels any more, as your LVs have expressive names already!
