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)
