Sounds like what you need is a tool that will change the label to host
specific labels. IE a shell script that will append -`hostname` to the
existing disk labels, and update /etc/fstab and /boot/grub/grub.conf
accordingly. Then you can run that shell script after setting the
hostname, and forever after that - the disk labels will be unique.

In fact - that would be useful since HAL mounts USB disks showing the
label on the desktop. IE if your hostname is enterprise :

/-enterprise
/boot-enterprise
/home-enterprise
/usr/local-enterprise

would be easily human recognizable - and hell, would be swell mount
points in /media for recovery.

cp -ar /media/home-enterprise/foo /home/

is a lot easier than trying to figure out if it
is /media/disk1 /media/disk2 etc.

I might start doing that manually - set up volume groups to have the
hostname in the Volume Group - IE

VolGrpEnterprise00
VolGrpEnterprise01
etc.

and appended to the label for non LVM - IE

/boot-enterprise

(/boot and swap are the only non LVM volumes I currently create)
