we cooked up a persistence unit for each module in the ear.  EE6 lets you put persistence-context-refs
and persistence-unit-refs in the application.xml which obviously have to refer to something
available at the ear level, so my conclusion is that we ought to be deploying persistence
units in an ear lib once for the whole ear.  (well, maybe also once in each app client).
