To-mate-o toe-maht-o. There really doesn't seem to be any real reason to create a new flag just because the granularity is different. The choice between _USER and _TYPE (and _ROLE for that matter) is arbitrary from a functional point of view. I say that since Smack has users, but not types or roles, _USER makes the most sense. > Certainly will confuse matters if a user has audit filters on SELinux > users in their /etc/audit/audit.rules and then boots a kernel with Smack > enabled. Somehow I doubt that will be their biggest concern.
