Unfortunately you have hit one of the biggest pain points I have found
with Chef. There is no way I have found to do this as they are
separate run contexts. I have tried all sorts of hackery to try to get
this working but I don't think it is possible without monkey patching
the core ... which I have yet to get to. It does mean that resources
are not composable but mostly they are still a better option than
definitions. It would be nice to have some way to be able to notify
the containing resource when things have changed.
