Naming the mountpoint by the label or volume name is not a smart 
practice. The only effect this has is to make using the cli less easy. I 
  label the discs that I make with rather long titles and would not like 
to type /media/Customer one system backup from 2/10/2006 with all the 
escape characters in order to change directories. Typing cd 
/media/cdrecorder and typing ls to list the files is a better idea.
I do like this information displayed on the desktop with the label though.

I noticed a problem someone was having on the Fedora-list with an lvm 
system with the same labels and LVM information for the disk he inserted 
into a USB enclosure then tried to access the information. I could not 
help him with the recovery of his data with the two exactly labeled LVMs.
I was able to recover my data from an LVM from a disk inserted into a 
USB enclosre on a system with regular partitions. I had to activate the 
LVMs and then manually mount the partions to directories that I had to 
create for mountpoints. If you still have a disk with the LVM install, 
you might be able to recover data from it using a traditionally 
partitoned system.

There could be a way, borrowing from the /media/crazy\ wacked\ out\ 
concept\ for\ volume\ names\ in\ media/

Performing ls on the directory is really impressive. Do I have this many 
directories or is one of them a name?

[root at cornette-lt media]# ls
cdrecorder  crazy wacked out concept for volume names in media  usbdisk

Ah! Let's use ls -la!
  ls -la
total 40
drwxr-xr-x  5 root root 4096 Feb 10 21:00 .
drwxr-xr-x 24 root root 4096 Feb 10 18:32 ..
drwxr-xr-x  2 root root 4096 Jan  6 06:08 cdrecorder
drwxr-xr-x  2 root root 4096 Feb 10 21:00 crazy wacked out concept for 
volume names in media
drwxr-xr-x  2 root root 4096 Jan  6 06:08 usbdisk

No let's change to 'crazy wacked out concept for volume names in media' 
directory.
cd crazy\ wacked\ out\ concept\ for\ volume\ names\ in\ media/

[root at cornette-lt crazy wacked out concept for volume names in media]# pwd
/media/crazy wacked out concept for volume names in media


LVM problems:

If LVM disks in USB enclosures are mounted, they could be inherit an 
appending to the volume group with a usb extension. Either that or 
random numbers for the volume groups could be used in the future for LVM 
naming. (8-character)
