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. Using this module ensures that cloud-init is entirely finished with modules that would be executed. An example to distinguish delay from timeout: If you delay 5 (5 minutes) and have a timeout of 120 (2 minutes), then the max time until shutdown will be 7 minutes, though it could be as soon as 5 minutes. Cloud-init will invoke 'shutdown +5' after the process finishes, or when 'timeout' seconds have elapsed. .. note:: With Alpine Linux any message value specified is ignored as Alpine's halt, poweroff, and reboot commands do not support broadcasting a message.
