I think this will only find packages which were installed by yum.
If you download an RPM to a machine (wget, scp, etc) and install it
using the 'rpm' command, it will not be found by 'yum list'. Seems
like a big oversight, but that was my experience on some RHEL5
machines I was an admin for. (I used RHEL4 more, and it still used
up2date. yum is much superior but I didn't have as much experience
with it.)
