BTW That should be 1, not 16.
The next release will that line built in.

Hmm. The ugly internal kernel kobject names appear courtesy of udev.  
Yuck. Don't use them for anything. They aren't meant to be there.

You can probably add some incantation to /etc/udev/rules.d/ to get
rid of them.


The algorithm LVM2 uses to choose the "nicest" display name for each 
device compares each new name it encounters with the current 
name and decides whether the new name is "nicer".
Unfortunately the final choice depends on the sequence in which the
names are encountered. This needs fixing.
