Yes, I'm running Ubuntu 8.04 and it uses UUID's. I ran
"ls -l /dev/disk/by-uuid" to see if the UUID's matched those in /etc/fstab 
and they did. From this am I correct in assuming that it's safe to reboot?
If it is, then we're back to my original question: is there any way to 
change /dev/sdb* back to /dev/sda* or should I live with it and edit 
fstab?
