For fstab, and most other places, they are just a partition with an odd name.  
/dev/VG0/LV0 might as well be /dev/sda1 as far as most tools are concerned.

That's a problem.

Agreed.  Removable media should not be mounted using the kernel device name 
(e.g. /dev/sda or /dev/sdb1), since it is likely to change.  I'd likely remove 
some of the comments just to make the active lines more visible.

If you use LVM snapshots, you shouldn't use UUIDs for LVM volumes, since the 
UUID of the file system in the snapshot will be the same as the UUID of the 
original file system.

So, /dev/DB-LVM* entries are fine, but the rest should probably be changed to 
LABEL=* / UUID=* entries.
