+## poweroff or reboot system after finished
+# default: none
+#
+# power_state can be used to make the system shutdown, reboot or
+# halt after boot is finished.  This same thing can be acheived by
+# user-data scripts or by runcmd by simply invoking 'shutdown'.
+# 
+# Doing it this way ensures that cloud-init is entirely finished with
+# modules that would be executed, and avoids any error/log messages
+# that may go to the console as a result of system services like
+# syslog being taken down while cloud-init is running.
+#
+# delay: form accepted by shutdown.  default is 'now'. other format
+#        accepted is +m (m in minutes)
+# mode: required. must be one of 'poweroff', 'halt', 'reboot'
+# message: provided as the message argument to 'shutdown'. default is none.
