But what if I like bugs?
You need to duck after that one. NOBODY in their right mind should prefer any proprietary UNIX to LINUX. Bugs linger for years in proprietary UNIX systems. They get killed out in the first three weeks after a new LINUX release. That's because tens of millions of people use LINUX and just a couple of leftover losers here and there still use Solaris, Iris, HPUX and the like.
Just set up a cuouple of servers on Fedora Core 4. Nice system, especially considering its free. In addition to that, you still get free patches and fixes through Redhat's up2date program.
