 Overrides:
 
- * To use a non-default URL for downloading base cloud images,
-   use the environment variable DIB_CLOUD_IMAGES
- * To download a non-default release of cloud images, use the
-   environment variable DIB_RELEASE
- * Alternatively, set DIB_LOCAL_IMAGE to the local path of a qcow2 cloud
-   image. This is useful in that you can use a customized or previously built
-   cloud image from diskimage-builder as input. The cloud image does not have
-   to have been built by diskimage-builder. It should be a full disk image,
-   not just a filesystem image.
