Bug Description

The EC2 DescribeImages API always reports a rootDeviceType of instance-store, even for the analogue of an EBS-backed AMI (i.e. an image that leads to a booted-from-volume instance).

This gives a false impression that the image in question is backed by a ephemeral root device, whereas in fact the root device is volume-backed.

    EC2 DescribeImages reports correct rootDeviceType

    Fixes LP 1024354

    A root device type of instance-store was incorrectly reported for
    boot-from-volume images (i.e. the analogue of EBS-backed AMIs).

    When comparing the block device mapping device name with the root
    device name, we now tolerate a missing leading '/dev/' path.
