Looking at my more-or-less standard FC6 system with updates
applied shows that in
   /etc/yum.conf
I have
   destroverpkg=redhat-release

However,
   rpm -q redhat-release
gives
   package redhat-release is not installed

However,
   rpm -qa | grep release
gives
   fedora-release-notes-6-3
   fedora-release-6-4

Would this represent a problem for an upgrade?
