I think you missed the point here - by explicitly specifying
sd0 at scsibus0 target 0 lun 0
in your kernel config file, you do wire down sd0 at scsibus0, ID 0 and
lun 0. Any disks that aren't wired down are caught by an entry like
sd* at scsibus? target ? lun ? # SCSI disk drives
and with the catch-all entry, device renaming will occur. It's not
exactly the same as the SYSV mechanism, but you can wire down disks
if you want to. This may even be the recommended practice - I can't
remember, but I always wire down disks.
