Fedora favors the leading edge, short release/update periods whereas the RHEL product (from which CentOS is derived) favors stable and long release/update periods. Where this is obvious are things like OpenOffice.org where Fedora Core 4 (at least test 2) has openoffice.org 1.89 and will obviously carry the 2.0 version in whatever form - even unstable if necessary and CentOS 4 will not have it unless RHEL updates which would be unusual for them to do so. Also, the RHEL packages tend to be much sparser and they don't include all the potential kernel modules (though of course you can compile) and they offer some things which aren't supported but clearly the package list is much shorter than Fedora and when you consider things like Fedora Extras and other repositories, Fedora has a much greater depth of available packages. With RHEL or CentOS, you have Dag packages (which isn't working to well these days - apparently because of reliance upon a host that's been flaky the past few days). As for your complaints... I hope that you put in entries in bugzilla.redhat.com about the problems such as cups-enable and the serial issues. That is how these things get fixed. The issue with the CD-ROM and noidma probably stems from the fact that RHEL 4 was released not too long after Fedora Core 3 and they would likely had similar kernels and hal files. The benefit of CentOS/RHEL is that CentOS/RHEL will provide a 'respin' or updated release of the boot/install CD's which will have newer kernels and detect the issues with hardware that may not have worked properly in the first release whereas the only 'respin' that Fedora ever sees is the next version release of Fedora Core. Myself, I use RHEL or CentOS for servers but Fedora for my desktop systems - I like having updated versions of things like gimp-2.2.4 (FC-3) vs. the earlier versions in RHEL. Craig
