Well clearly there is something about this that I don't understand. :) If you have a sufficiently small number of ports, sure it's possible that you *might* not have to recompile. However if you're talking about a desktop system with X I guarantee you that if you clean out all the old stuff in the base after doing a major version upgrade then there are things in /usr/local/ that are linked against libs that no longer exist. How much that affects you is a YMMV of course. Meanwhile my larger point was that it doesn't matter whether COMPAT_FREEBSD8 exists or not, whether some upgrades appear to work or not, etc. When you do a major version upgrade your safest bet is wipe out your old stuff and start over from scratch. You'll waste more time trying to find ways around doing that than you would spend just doing it. :) Doug -- You can observe a lot just by watching. -- Yogi Berra Breadth of IT experience, and depth of knowledge in the DNS.
