-- | Requests a reboot of one or more instances. This operation is asynchronous;
-- it only queues a request to reboot the specified instances. The operation
-- succeeds if the instances are valid and belong to you. Requests to reboot
-- terminated instances are ignored. If a Linux/Unix instance does not cleanly
-- shut down within four minutes, Amazon EC2 performs a hard reboot. For more
-- information about troubleshooting, see Getting Console Output and Rebooting
-- Instances in the Amazon Elastic Compute Cloud User Guide.
