+# Description:          Run ifdown on interfaces authenticated via

+#                       processes before networking is stopped causing each

+#                       daemon to be terminated abrubtly.
+#                       Since initscripts package version 2.86.ds1-48 an
+#                       interface exists to omit process id's from sendsigs. If
+#                       this interface is present this script is a no-op.
