Excuse me, but isn't this exception confusing, for DEFAULT_SECURITY_TOMOYO
and DEFAULT_SECURITY_DAC are "opt-in" whereas DEFAULT_SECURITY_SELINUX and
DEFAULT_SECURITY_SMACK and DEFAULT_SECURITY_APPARMOR are "opt-out" ?

If SELinux/Smack/AppArmor people think this mixture is fine, I'm fine though...
