These won't work. It'd drive programs nuts. What's different between
sd0 and sd00 to a program that looks at the device numbers as integers?

How hard is it to post a little piece of paper next to the machine with
the disk->controller:id mappings?
They're on the 'dmesg' and system log too:
(ncr0:3:0): "PLEXTOR CD-ROM PX-4XCE 1.00" type 5 removable SCSI 2
cd0(ncr0:3:0): CD-ROM
cd0 - device/driver
(ncr0 - controller/device
:3 - SCSI ID
:0) - LUN
: FAST SCSI-2 175ns (6 Mb/sec) offset 8. - device description &
information.
