Subject: [refpolicy] [PATCH] second strict patch take 3
Message-ID: <20170420145112.jcxkiknyy2yb4qpu@athena.coker.com.au>
To: refpolicy@oss.tresys.com
List-Id: refpolicy.oss.tresys.com

Changed some of the things that Guido didn't like.

Also removed a lot of duplicate rules from init.te.

As an aside we need to merge the 2 ifdef systemd_init sections.  That will be
a separate patch.
