+      NetworkManager process handles the following signals:

+          The signal causes a reload of NetworkManager's configuration.
+          Note that not all configuration parameters can be changed at
+          runtime and therefore some changes may be applied only after
+          the next restart of the daemon. The signal also forces a
+          rewrite of DNS configuration.
