22	help
23	  This option sets the default value for the kernel parameter
24	  'apparmor', which allows AppArmor to be enabled or disabled
25          at boot.  If this option is set to 0 (zero), the AppArmor
26	  kernel parameter will default to 0, disabling AppArmor at
27	  boot.  If this option is set to 1 (one), the AppArmor
28	  kernel parameter will default to 1, enabling AppArmor at
29	  boot.

48
49       help
50         This option selects whether sha1 hashing of loaded policy
51	 is enabled by default. The generation of sha1 hashes for
52	 loaded policy provide system administrators a quick way
53	 to verify that policy in the kernel matches what is expected,
54	 however it can slow down policy load on some devices. In
55	 these cases policy hashing can be disabled by default and
56	 enabled only if needed.
