If /smack/onlycap is empty (unset or null-string) privilege
is enforced in the normal way.

If /smack/onlycap contains a label only processes running with
that label may be MAC exempt.

If the label in /smack/onlycap is the star label ("*") the
semantics of the star label combine with the privilege
restrictions to prevent any violations of MAC, even in the
presence of privilege.

Again, this will be independent of the privilege scheme.
