I assume most of you who upgraded to 2.0 used the Upgrade2.0
Application?
I tried the "complete reinstallation" route, and this is what I
got:

UH-OH! It never did THAT before. So I brought up 1.0a again and
typed the same thing:

Then I switched to 2.0 and did a command-line builddisk with the
-n option. (This being equivalent to the way things would have
been had I used Upgrade2.0.)
So, did NeXT have the disk geometry "wrong" since Day 1 or is the
"improved" disktab hosed? This is a genuine NeXT-supplied disk--
it's supposed to work, right?
