This is the right place to look at. As hardware detection has become
my dynamic, it has been harder to guarantee that the order hardware is
discovered in will always be consistent. This is also one of the
reasons that Ubuntu uses UUIDs in /etc/fstab instead of block device
names.

See /etc/udev/rules.d/60-persistent-storage.rules, take a look at the
manpage for udev, then use the links in /dev/disk/* instead.
