A quick look through some manuals shows that SunOS 3 (same timeframe) appears to have had
a user-friendly initial setup program but it's not clear to me if it could be used
after an installation to deinstall/modify/upgrade/etc.
I don't think it could. I also remember that SunOS 4's installer was somehow
much more rudimentary. I remember (for both) that things like patches were just tarballs
or some equivalent: there was no registry I think. However my memory is not reliable.
