Seth, You mentioned that I could use a directory containing links to RPMS and run yum-arch on it to create the header info for that directory. However, when I tried it, I got : No rpms to look at. Exiting. The same yum-arch works fine on the directory actually containing all the RPMS. I was just testing to see if I could create a subset of those RPMS in another directory via links.
