Red Hat/Fedora Usage

We currently have a mirror of Red Hat and Fedora and several 3rd party packagers available. While these mirrors aren't exactly what's on their servers (we do exclude some architectures and older releases), it should be fairly close.
In addition to the mirrors, we have our own repository (ayo) that includes all of Red Hat/Fedora's core files, updates, and the other 3rd party packages all in one central place.
Yum configuration files can be found here.
Mike Sangry also provided some information how to use up2date with our mirror:
Simply add the following TWO lines to /etc/sysconfig/rhn/sources
    yum CTI-FC3 http://distro.ctinetworks.com/ayo/fedora/3/$ARCH/core/
    yum CTI-FC3-updates http://distro.ctinetworks.com/ayo/fedora/3/$ARCH/updates/
There are two rather similar lines in the 'sources' file, too. Users can either comment them out with a '#' or leave them there. If they leave them there the two additional lines will appear as other channels. These can be unchecked when running up2date manually.
