[15:28] <cpaelzer> so adding a deny (btw I can only add to places users can't 
modify) they can't allow it later right?
[15:28] <jjohansen> cpaelzer: correct
[15:28] <cpaelzer> so how could I silence access to a given path
[15:28] <cpaelzer> but have the chance for user to later allow it?
...
[15:31] <jjohansen> unfortunately deny is the only way currently to control 
quieting atm
[15:31] <cpaelzer> ok, so for now I have to choose between a) the denial is 
slightly annoying now, but users can allow it later AND b) silencing it now but 
the few users that want to allow it will be unable to do so
[15:31] <cpaelzer> is that summary correct?
[15:31] <jjohansen> yes
[15:31] <cpaelzer> thanks

Due to the above I think I could make virt-aa-helper:
 - if a </pmem> is present add allowing the paths
 - if no </pmem> is present add a deny rule to silence the denials

The only case left open would be systems that start without any pmem and
want to hot-add it later. Those should be pretty rare one would think
(even rarer than nvdimms on its own already are).

Next steps:
 - get a full assortment of possible paths (I hope Adam or Jeff can help)
