+This patch prevents nsd from attempting to unlink the pidfile on nsd
+shutdown.  The reason for this is because we get a permission denied
+error in nsd.log when it attempts to do so.
+
+I think this is needed because of how normal OpenRC init scripts are
+designed and handled.
+
+See the included /etc/init.d/nsd (nsd.initd) for my conversion of the
+nsdc script that's normally distributed with nsd.  The included nsdc
+script is a wrapper for the converted OpenRC init script, designed to
+maintain compatibility.
