Yes, or something along the lines of the SysVr4 disk naming
convention of c0t0d0s0, where c0 is the controller, t0 is something I
cant remember off hand, d0 is the disk number on the controller (the
SCSI ID), and s0 is the slice number (partition). We might need to
add onto that a bus number for those machines with multiple SCSI
and/or EISA busses.

That sounds a reasonable idea, should make the changes from the
existing default minimal, and allow the system to grow (it should
also include CDROMs and tape drives too).
