The deploy kernel & ramdisk are created by diskimage-builder, and
contain a small "agent" used by Ironic when provisioning the node.

The user kernel & ramdisk must be separate. These should be the same
kernel & ramdisk contained in the user-specified image, eg. the image
you are requesting when issuing "nova boot --image $UUID".
