-=head2 Message Queue rules
-
-AppArmor supports mediation of POSIX and SYSV message queues.
-
-AppArmor Message Queue permissions are implied when a rule does not explicitly
-state an access list. By default, all Message Queue permissions are implied.
-
-AppArmor Message Queue permissions become more restricted as further information
-is specified. Policy can be specified by determining its access mode, type,
-label, and message queue name.
-
-Regarding access modes, 'r' and 'read' are used to read messages from the queue.
-'w' and 'write' are used to write to the message queue. 'create' is used to create
-the message queue, and 'open' is used to get the message queue identifier when the
-queue is already created. 'delete' is used to remove the message queue. The access
-modes to get and set attributes of the message queue are 'setattr' and 'getattr'.
-
-The type of the policy can be either 'posix' or 'sysv'. This information is
-relevant when the message queue name is not specified, and when specified can be
-inferred by the queue name, since message queues' name for posix must start with '/',
-and message queues' key for SYSV must be a positive integer.
-
-The policy label is the label assigned to the message queue when it is created.
-
-The message queue name can be either a string starting with '/' if the type
-is POSIX, or a positive integer if the type is SYSV. If the type is not
-specified, then it will be inferred by the queue name.
-
-Example AppArmor Message Queue rules:
-
-    # Allow all Message Queue access
-    mqueue,
-
-    # Explicitly allow all Message Queue access,
-    mqueue (create, open, delete, read, write, getattr, setattr),
-
-    # Explicitly deny use of Message Queue
-    deny mqueue,
-
-    # Allow all access for POSIX queue of name /bar

-User namespaces are part of many sandboxing and containerization
-solutions.  They provide a way for a non-system root process to be
-root within the container. Unfortunately this opens up attack surface
-in the kernel and has been part of several exploit chains. As such
-AppArmor can be used to restrict the creation of user namespaces to
-select processes.
-
-User namespace permission are implied when a rule does not explicitly
-state an access list. The rule becomes more restrictive as further
-information is specified.
-
-Note: user namespace creation may be restricted so that it is not
