11	  This selects the Simplified Mandatory Access Control Kernel.
12	  Smack is useful for sensitivity, integrity, and a variety
13	  of other mandatory security schemes.

21	  Enable the bring-up ("b") access mode in Smack rules.
22	  When access is granted by a rule with the "b" mode a
23	  message about the access requested is generated. The
24	  intention is that a process can be granted a wide set
25	  of access initially with the bringup mode set on the
26	  rules. The developer can use the information to
27	  identify which rules are necessary and what accesses
28	  may be inappropriate. The developer can reduce the
29	  access rule set once the behavior is well understood.
30	  This is a superior mechanism to the oft abused
31	  "permissive" mode of other systems.

49	help
50	  Sending a signal has been treated as a write operation to the
51	  receiving process. If this option is selected, the delivery
52	  will be an append operation instead. This makes it possible
53	  to differentiate between delivering a network packet and
54	  delivering a signal in the Smack rules.
55	  If you are unsure how to answer this question, answer N.
