Because device nodes like /dev/sd* get assigned depending on the order
in which the kernel loads device drivers and in which order the device
drivers discover the drives.  The ordering has never been guaranteed
to be the same, it's just much more noticeable now that much more
stuff is hot-pluggable.

Even better is to refer to drives in fstab by UUID.  Labels aren't
unique, which can be a problem if you need to move disks between
different systems.  Mounting filesystems by UUID is supposed to happen
by default if you install with F9.
