Hello Scientific Linux folks, How are you generating the updates repos' updateinfo.xml? (updateinfo.xml.gz) I had thought it came only from official Red Hat Network (RHN) repositories or their projects EPEL or Fedora, but I see it in Scientific Linux: * SCL 5.10: http://linuxsoft.cern.ch/cern/slc510/updates/x86_64/RPMS/repodata/ * SCL 6.5: http://linuxsoft.cern.ch/cern/slc65/updates/x86_64/RPMS/repodata/ Shatil (@shatil)
