Change 93194 by rwatson at rwatson_zoo on 2006/03/12 15:24:27

	Add a top-level security.audit sysctl node, which will be present
	regardless of audit compiled in.  User space applications will be
	able to test for the node to decide whether or not to invoke audit
	system calls, which may improve the behavior of applications like
	login when running on older kernels (unsupported, but often used
	configuration).
