For our Red Hat Server Farm we need a Mature Configuration Management. We searching now long time and @ the Linux Tag 2008 in Berlin I saw the Presentation from Francesco witch was very good, because he is IMHO the first Guy he really understand our Problem: For 1 Server we have with all Tierlevels at the End arround 7 Servers to manage!

The Red Hat Satellite Server is for the Configuration Management, after a lot of Disscussions with other Sysadmins not the best Solution. It works but nothing more. Now with the spacewalk Project there will be a big change, but that takes time.
