There is one more point to that. We are eventually going to have an SSA
device driver, and SSA tends to be used in large server installs. Each
disk is presented to the OS as a single SCSI disk ... so I think we need
a major change in disk numbering, not just 16 more devices by one more
major number. 16 bit minors (and majors, for that matter) would be the
cleanest solution IMHO. That's what commercial Unixes tend do offer.
