repo management and snapshots

Hi I looked around through the documentation but could not get a description of how to do "repo" snapshots. I might have missed it or not have a full grasp or understanding yet but would appreciate anyone sharing thoughts on how to do it. Very simply I want to be able using only cobbler to create a snapshot of a repository and called it for example RH5.6-Feb which should contain the base repo plus all updates that has been releases up until that point. I want to be able to then create monthly snapshots for example and when I build a server build it against one of these snapshots. If you can already do this in cobbler I would appreciate some guidance or if not if anyone could share how they achieve this with cobbler. You can do this in spacewalk but I am not sure how much is spacewalk and how much is cobbler and I am keen to not re-invent the wheel. For various reasons at the moment unfortunately I can't use spacewalk to manage this so the solution has to be native to cobbler. Best Regards -- Gerhardus Geldenhuis
