Description of problem:
The package rootfiles-8.1-1.1.1.noarch was pulled straight from RHEL and was not
rebuilt. It was simply resigned. This means that the vendor field still says
"Red Hat, Inc." .
Not sure if this was intentional or not, but it doesn't seem proper.
Talking with Jon Stanley, he is going to rebuild all the Fedora packages with
the correct vendor that need them. Assigning to him.
The problem was actually solved another way in Spacewalk (which was the initial reason this was noticed). We now take into account the md5sums of packages (thereby catching patches signed with different keys). The root of the problem was that many vendors (RH, Fedora, CentOS) included files with the same NEVRA but signed with different keys, and Spacewalk/Satellite keyed off of the NEVRA for determining the uniqueness of a package.
This bug can be closed.
