Resize down on drives is a nono! CPU and ram that can be done

If the flavor's disk is 10GB, and the image is 2GB, cloud-init will try to expand the file system to the full 10GB on boot. That would prevent resizing down to a flavor with a smaller disk size, even if you only have a couple gigs of data on the disk.
