Hmmm ... I don't do steps two or three, and I'm using gcc 2.5.7 and Ultrix
as - I wonder how come I'm so lucky?

Never saw this, but I did get swapinit panics until I installed Jonathan
Stone's patches.

*This* I've seen.  Without /sbin/init, the kernel takes a "no init" panic.
With /sbin/init, it hangs.

Well, I tried a different drastic step the other day.  I reinstalled Ultrix
(4.3) from scratch, then put the netbsd kernel in / and booted it instead
of vmunix.  It succeeded; I got a single-user-mode shell prompt.  (This is
the same kernel that I built on 11/11 which used to just hang.)

I don't really know what to make of this ... but NetBSD boots on my 5000/25
now!  Of course, the old-style Ultrix file systems get mounted read-only,
which drastically cuts down on the system's usefulness ...
