In case it escaped your attention, the SysV device names are extremely
descriptive (and thus useful), esp. for SCSI devices.  For example,
c1t2d0s5 is {controller-1}, {scsi_target-2}, {disk_unit-0}, and
{partition/slice-5}.  Hard to forget what physical thing that name

I wouldn't argue with splitting these names intoe sub-directories where
appropriate, but for SCSI, I don't think the number of addressable units
is really that high to require separate directories for each target or
