Description of problem: We've had an issue when re-registering a system, where new or updated packages in the newly subscribed channels won't install because they're not in the local yum metadata, even after registration. A 'yum clean' or similar should be added to the bootstrap.sh script or rhn_register process so that yum metadata is rebuilt and updated/new packages in newly subscribed channels are made available to the system.
This can be done by customer by manually editing the bootstrap script that they use. This type of issue of doing a yum clean to force download of new meta-data is independent of registrations. I don't see us implementing this globally for all customers. Closing deferred. Cliff
