While this temporary policy worked, we want to remove this at some
point. There should be some sort of service to let apps know when they
are low on disk space. This policy addition was 'ok' for the camera-app
because it is an Ubuntu Core app and written by Canonical, but non-
Canonical apps won't be allowed to add these accesses. They must use the
future service to get low disk space notifications.

  moment generate the following denials:
