Right, that's the generic Salt approach. But I wonder if we need to take
some extra cautions here, e.g. when it comes to the order in which nodes
are upgraded?

I'm not sure if it's safe to do this in parallel, as it might result in
unexpected service restarts on all nodes at the same time. Salt by
itself does not have any knowledge of the various roles of a Ceph
cluster and their dependencies. Or maybe that's not really a valid concern?
