 The consensus was that there's *NO* difference whatsoever between
having a disk on the internal SCSI ports compared to having it on the
external SCSI. "It's all the same bus." The rumor I'd been told about
having your swap & root on an internal disk for better performance
turned out to be hog-wash.
 So I'm going to go ahead with the move.
