There is a trick to this. If you update a IX server, 9.2 machines will not be able to execute the pieces of unix that are linked to that 9.5 server. For example, most of my machines have a link for etc to //h/bsd4.2/etc. As soon as I updated //h/bsd4.2/etc the 9.2 machines which had links to this etc directory could not execute commands out of etc anymore. The thing to do is bring up full 9.5 on a machine that has no other machines linked to it (or machines linked to it you don't care about for a while) and install it from there. Then do your IX servers last. I also found the /etc/syslog.conf to be in error. Other than that, the install went very smoothly. If you have a custom optional software tape, have something to do while you wait for it to look all over the tape with each software package. If I had some extra time, I would write a "real" installation procedure.
