Seth, I need to implement a local repository for fedora core 4 in a yum server machine (RHEL 3.0as) with yum-2.0.7-1.noarch.rpm installed. The questions are: can I to continue using this version in fedora client safely?. The Duke webpage recommends yum 2.4.x.src.rpm, do you know any incompatibility to use both? (lamentably there isn't a noarch for download in this version). Regards.
