That was a bad example, I realized that afterwards, however, this is a better one:
SCSI drives get their devices assigned as the chain finds then, so if you have the
first drive as ID1, and the second as ID5, and you have them setup as / and /usr.
You'll find this in your boot up log:
ID1 = sda1 /
ID5 = sdb1 /usr
Now, you decide to add a third drive, with ID3, mounted as /var. Now all of a
sudden, what USED to be sdb isn't anymore. It's now sdc:
ID1 = sda1 /
ID3 = sdb1 /var
ID5 = sdc1 /usr
However, as far as your fstab is concerned, it is still mounting /dev/sdb1 as
/usr, which isn't true anymore. You have to go manually edit your fstab to fix that
problem. However, if you had LABELs instead, it doesn't care WHAT device it's on, all
it will do is mount the LABEL instead, which will always be correct.
Learn to use them.
