Never mind, I rebuilt ufsboot, and the system now boots okay off of
a disk, although it still seems to dislike rebooting without a full
reset.  Huh.

Oh, well.  It's not like it resets more than once a month.  Did I
ever mention that NetBSD has been *really* stable for me on this 3/60?
I can crash it only one way, and I'm not even sure I can still do that.
