Hi Kilian, have you compared download sizes for repos vs. having each node go online? In my experience, repos contain WAY more packages than are actually installed on cluster nodes. Saving bandwidth only works with a reasonably high number of nodes of the same architecture. Delta packages, if available, help to even further reduce bandwidth. As does a proxy tailored to your needs.
Controlling versions is easier though with local repos. Could also be done with config mgmt, and more flexible so. But local repos are the easy way for sure.

We usually do it by either mirroring those repositories on the management node (which is good to make sure all the nodes get the same version of the repo at any given time, and to save bandwidth), or by adding online repositories on the nodes in postscripts.
