I am currently mirroring the following bundles from NCC onto my ZLM sevrver

Catalog : SLES11-Updates Bundle : SLES11-Updates-bundle
Catalog : SLES10-SP2-Updates Bundle : SLES10-SP2-Updates-bundle

My question is are these bundles automatically updated with the latest patches from Novell?

I have been mirroring them for a few months and there doesn't appear to be many\any updates made to the bundle version within ZLM
