Brunel running SL4 cluster

The worker nodes of dgc-grid-40 are now running the glite worker node release on SL4. It is passing the ops SAM tests and the VO tests that have run recently. There was a problem with LHCb production jobs trying to use edg-brokerinfo rather than glite-brokerinfo which I reported and they have now fixed. CMS production jobs have also completed successfully. Steve Lloyd's ATLAS tests pass apart from the 'New Package' part. Steve's comment was "My tests are still running release 12.0.6 for which the requirement is SL3 so they shouldn't really go into SL4 machines...this problem will go away when I switch to release 13.0.X as that's supposed to work on SL4". ATLAS production jobs seem to run OK but there seems to be a problem copying the output files back.
