-- Creates an Amazon EBS-backed AMI from an Amazon EBS-backed instance that
-- is either running or stopped.
--
-- If you customized your instance with instance store volumes or EBS
-- volumes in addition to the root device volume, the new AMI contains
-- block device mapping information for those volumes. When you launch an
-- instance from this new AMI, the instance automatically launches with
-- those additional volumes.
