+### BEGIN INIT INFO
+# Provides:          telegraf
+# Required-Start:    $all
+# Required-Stop:     $remote_fs $syslog
+# Default-Start:     2 3 4 5
+# Default-Stop:      0 1 6
+# Short-Description: Start telegraf at boot time
+### END INIT INFO
+
+# this init script supports three different variations:
+#  1. New lsb that define start-stop-daemon
+#  2. Old lsb that don't have start-stop-daemon but define, log, pidofproc and killproc
+#  3. Centos installations without lsb-core installed
+#
+# In the third case we have to define our own functions which are very dumb
+# and expect the args to be positioned correctly.
+
+# Command-line options that can be set in /etc/default/telegraf.  These will override
+# any config file values.
