Run VMware workstation on a Fedora machine, going through the kernel updates, and then get back to me (or VMware server, it has the same problems). And the problem isn't with the binary parts; it is with the open-source parts. I shouldn't have to recompile stuff every kernel revision. The short of it: even Linus will admit that the 2.6 kernel series is not stable between versions; not only does he admit it, but he likes it and thinks it is a good thing. Not only does the binary interface change, the source interface changes. Go to the vmware forums and search on 'vmware-any-any' and read the threads. It's not limited to Fedora, either; Ubuntu does the same thing. It's an upstream (kernel) disease that has decreed that ABI and API compatibility is not important between new versions. So between 2.6.19 and 2.6.20 a source patch had to be made to the open-source portions of vmware workstation (and vmware server) to get it to even compile; between 2.6.20 and 2.6.21 the same thing. Between 2.6.21 and 2.6.22 the same thing. It's bad enough to have to recompile every time a new kernel is sucked in by yum; it's worse when you have to track down what has changed and how to patch the vmware source to be able to recompile. I just track the vmware-any-any patches and stay a week or so behind on kernel updates; I don't have time to dig into the kernel changelog to see what they changed this week. And, of course, I only run Fedora 7 on development desktops/laptops; the servers get CentOS, not Fedora, and production desktops get something else. I want the same thing Les wants: a stable kernel and newer, frequently updated userland. The CentOS Plus repo begins to get it; for KDE stuff KDE-Redhat installed on CentOS gets it. In fact, KDE-Redhat on a CentOS base is just about ideal, if you use KDE (and I do); this is what I put on my production desktops that run Linux. Incidentally, Les is quite active over on the CentOS lists, so, he's well aware of that option. Oh, just in case you are wondering about my 'history' check out the changelog for the PostgreSQL RPM's prior to version 8.0. -- Lamar Owen Chief Information Officer Pisgah Astronomical Research Institute 1 PARI Drive Rosman, NC 28772 (828)862-5554 www.pari.edu -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
