Hi there, I tried ZCM (new version of ZLM) i only subscribed to the patch management module. I found the tool extremely buggy. So after a while I decided to found a new solution and that is novell SMT which is free. Its also a bit buggy but free. If you find a great SM tool for both rhel and sles please let me know. You cant really controle which packages to pathc in greater details using puppet. That would imho be impossible in the longer run.
