Thanks for the response.
For a system that wants to control a few daemons, is there a
recommended pattern from selinux ?
I read this blog about unconfined domain (unconfined_t), maybe this is one way ?
https://wiki.gentoo.org/wiki/SELinux/Tutorials/What_is_this_unconfined_thingie_and_tell_me_about_attributes

I have two questions on unconfined domain:
1> Is unconfined_t domain supported in SECURITY_SELINUX_DEVELOP=n mode ?
2> will unconfined_t domain log also as permissive domain ?

Thanks
Jeff
