We do use UUIDs (or LABELs), but that doesn't solve the LVM problem, 
because the given device "/dev/somevg/somelv" only appears after LVM has 
been activated! I am thinking about using udev scan for LVM volume 
groups each time a hard drive appear that contains an LVM device. But 
that is a topic for another place.
