I’ve just read in LWN about recently announced Fedora Tracker. The goal of the project is to have a central database of apt and yum repositories with search facilities. This sounds like a very nice idea, since finding some Fedora RPM packages is not an easy task.
I’ve check it out and there is plenty of repositories already in. There is also a Submit form for missing information. I wish for this project to live and grow, since it has the potential to be more useful than RPMfind.Net.
