Ultrix Upgrade 1.2 to 2.2

We run Ultrix 2.0-1 kernels with 4.3BSD everything else on our VS2000
and MVII/GPX workstations.  Most of the machines here at UW run 4.3BSD
with our UW fixes in them; we couldn't live on Ultrix with the stock
stuff and no source so we got rid of as much Ultrix as we could and put
on the 4.3BSD stuff for which we had source.  We'd run full Waterloo
4.3BSD on everything, except at the time we got the VS2000 only Ultrix
kernels ran on it.  So we keep the Ultrix kernel because we have to.

We got some VS3200 and VS8000 workstations that needed Ultrix 2.4 and
had to boot over the net.  So, I installed the 2.4 RIS stuff on one of
our 2.0-1/4.3 GPX systems and ran /etc/ris to add the 3200 and 8000
clients.  The resulting load files didn't quite netload correctly.  I
discovered a couple of system .h files that had changed from 2.0-1 to
2.4; replacing these with the 2.4 versions and re-running /etc/ris
created loader files that allowed the VS3200 and the VS8000 to boot
Ultrix 2.4 over the net from the hybrid 2.0-1/4.3 GPX system.

Now that tahoe supports the both the VS2000 and VS3200 series, maybe we
won't have to run Ultrix kernels any more.  Not having source is a real pain.
