I just installed a fresh copy of Redhat 9. Then I grabbed the yum from http://apt.freshrpms.net/
and ran 'yum update'. It updated a lot of stuff, but when I ran 'yum list' I noticed that it didn't list additional software I could install (e.g. irssi, firefox). So, then I added a line to yum.conf for the dag repository (baseurl=http://apt.sw.be/redhat/9/en/i386/dag). Now, I'm able to install additional software.
What other repositories should I add for additional software? Also, I noticed that FedoraLegacy supports Redhat 9, but do I need to add that repository if ayo already provides the os updates?
