** Description changed:
- When creating a volume from a glance UEC image, the RBD driver fails to
- combine the rootfs, kernel, and ramdisk into a single volume suitable
- for booting an instance. Instead, only the rootfs is written to the
- volume, which is empty. This causes nova's boot-from-volume operation
- to fail if the volume is ceph-backed and the image is of type UEC.

By contrast, the same operation on an LVM volume yields a volume that
contains all the necessary pieces to boot an instance.
This is also likely the reason for recent ceph CI job failures in
test_volume_boot_pattern, as tempest executes this exact set of
operations.

stable/liberty branch without any changes.
