After futzing with this for a couple of weeks now, I'm resorting to
asking what is wrong with this picture:

  I boot a locally built -current (1.2G) GENERIC kernel on a Sparc-1
  It finds the scsi disk (sd0) and reports:

    root on sd0a dumps on sd0b
    no file system for sd0 (0x700)
    cannot mount root, error = 79

  If I give it "ffs" for the file system, it reports

    cannot mount root, error = 6

So what am I (or is it) doing wrong?  (I'm assuming pilot error rather
than a bug for now; ergo, no bug filed.)

Thanks.
