#     
#     Pull keyring ACL support from David Howells:
#      "This changes the permissions model used by keys and keyrings to be
#       based on an internal ACL by the following means:
#     
#        - Replace the permissions mask internally with an ACL that contains a
#          list of ACEs, each with a specific subject with a permissions mask.
#          Potted default ACLs are available for new keys and keyrings.
#     
#          ACE subjects can be macroised to indicate the UID and GID specified
#          on the key (which remain). Future commits will be able to add
#          additional subject types, such as specific UIDs or domain
#          tags/namespaces.
#     
#          Also split a number of permissions to give finer control. Examples
#          include splitting the revocation permit from the change-attributes
#          permit, thereby allowing someone to be granted permission to revoke
#          a key without allowing them to change the owner; also the ability
#          to join a keyring is split from the ability to link to it, thereby
#          stopping a process accessing a keyring by joining it and thus
#          acquiring use of possessor permits.
#     
#        - Provide a keyctl to allow the granting or denial of one or more
#          permits to a specific subject. Direct access to the ACL is not
#          granted, and the ACL cannot be viewed"
