I wish it were. No. This is a rock bottom low budget school situation. It's a refurbished amd duron wind tunnel with a whacking 40GB hard drive.

That would give some hope as > my current plan is to reinstall 10.2 (instead of upgrading from 10.1 to > 10.2) and copy the needed configurations. I think you just convinced me. No one could help you then, there are no similar situations I can google and I'm totally on my own. It's not worth the hassle. I do a new install, create 200 new users and make the old /home directory available to them for a while so that they can copy the stuff they need. 2 hours work. The alternative of stale nfs handles, locks, or WHY would probably take two weeks. Or tell me otherwise. If I do have a go you'll be the first to know.
