Well, let's explore that.

Suppose we have something which probes the various SCSI and IDE devices
and examines the various identity strings they return.

DKA500 says its and RRD45. Okay, that's a CD-ROM.

BUT WAIT!! DKB400 says its an RRD42!

....and DQA0 says is a DVD-ROM of some sort, DQB0 says its a CD-RW and
DVD+/-R!

Hhmmm... which do we ASSIGN as the equivalence string of the $CD,
$CD_ROM, etc.logical name? ...$DVD, etc.?

How 'bout if there should happen to be both a DVA0: and a DVA1:(DVB0:?)
which both say they are RX33s? Which becomes $FLOPPY or whatever?

Probably best if the SysAdmin sets those up for each individual machine.

My $0.02...

IIRC, when Ultrix was replace with OSF-1
similar changes were made in the /dev naming conventions.

Does it make any brash assumptions?
