Power State Change
------------------
**Summary:** change power state
This module handles shutdown/reboot after all config modules have been run. By
default it will take no action, and the system will keep running unless a
package installation/upgrade requires a system reboot (e.g. installing a new
kernel) and ``package_reboot_if_required`` is true. The ``power_state`` config
key accepts a dict of options. If ``mode`` is any value other than
``poweroff``, ``halt``, or ``reboot``, then no action will be taken.
The system
can be shutdown before cloud-init has finished using the ``timeout`` option.
The ``delay`` key specifies a duration to be added onto any shutdown command
used. Therefore, if a 5 minute delay and a 120 second shutdown are specified,
the maximum amount of time between cloud-init starting and the system shutting
down is 7 minutes, and the minimum amount of time is 5 minutes. The ``delay``
key must have an argument in a form that the ``shutdown`` utility recognizes.
The most common format is the form ``+5`` for 5 minutes. See ``man shutdown``
for more options.
Optionally, a command can be run to determine whether or not
the system should shut down. The command to be run should be specified in the
``condition`` key. For command formatting, see the documentation for
``cc_runcmd``. The specified shutdown behavior will only take place if the
``condition`` key is omitted or the command specified by the ``condition``
key returns 0.
