Hello All,
I am attempting to restore 4.3BSD-Tahoe to a usable state on the VAX. It
appears, based on the work that I have done already, that this is
possible. Starting with stock 4.3BSD I got a source tree into /usr/tahoe
and using it I replaced all of /usr/include and /sys, recompiled and
replaced /bin, /lib, and /etc, recompiled a GENERIC kernel, and from there
I was able to successfully reboot using the new kernel. As far as I can
tell (fingers crossed!) the hardest part is over and I'm in the process of
working on /usr.
My question is: how was this sort of thing done in the real world? If I
was a site running stock 4.3BSD, would I have received (or been able to
request) updated tapes at regular intervals? The replacement process that
I have been using is fairly labor intensive and on a real VAX would have
been very time intensive too. Fortunately two to three years' worth of
changes were not so drastic that I ever found myself in a position where
the existing tools were not able to compile pieces of Tahoe that I needed
to proceed, but I could easily imagine finding myself in such a place.
(This was, by the way, what I ran into when attempting to upgrade from
2.9BSD to 2.10BSD, despite a fully documented contemporary upgrade
procedure).

Hi Henry,
I expect folks who actually ran this can weigh in with the 'real world'
perspective. What I can offer is that the document entitled, "Installing
and Operating 4.3BSD-tahoe UNIX* on the VAX" by the folks doing the
release (CSRG) is probably canonical:

There's a section on migrating 4.2/4.3 to tahoe and the like. After it's
up and running, it looks a little shy on details, but getting there
seems well enough documented. If it's anything like 1bsd+, it seems like
it was usually unpack and copy to the right locations, with the
occasional compile with the right options thrown in.
