  On one of my VAXen at home, I'm running Ultrix v3.1 (it's all I
have) and it does a pretty decent job of calculating default partition
tables for new (unlabeled) disks.  I've got an Emulex QD32 disk
controller, which sits in a Q-bus and emulates two RA-series MSCP
disks.  After formatting a new disk of arbitrary geometries, I boot up
Ultrix, and the RA device driver comes up with its own partition table
for the disk.  It usually does a pretty good job.

  Is this something that would be practical for NetBSD to do?  Or even
