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)
