You don't *HAVE* to use labels, but it can be awfully handy in cases
like this. I ran into the craziness with the drivers from Promise for
their ATA Raid chipsets, where their "Linux support" driver was
basically an older version of the standard Linux drivers which they
had carefully edited to make their drivers put /dev/hde and /dev/hdf,
the drives on their add-on conroller chipsets, to /dev/hda and d/ev/
hdb. It drove mem *NUTS* when I tried to do a kernel upgrade!

It's also very handy with SCSI type devices which have, since he
beginning of SCSI support, tended to renumber themselves fairly
randomly as SCSI devices are detected in sequence and labeled that
way, rather than using the SCSI ID number.
