-   `ami_root_device` (RootBlockDevice) - A block device mapping describing the root device of the AMI. This looks
    like the mappings in `ami_block_device_mapping`, except with an
    additional field:
    
    -   `source_device_name` (string) - The device name of the block device on
        the source instance to be used as the root device for the AMI. This
        must correspond to a block device in `launch_block_device_mapping`.
