Monty Taylor af2862a2be Add minimal ubuntu and centos base elements
There are times when a much more stripped down base image is desired
over the distro cloud images. For instance, Infra would like some base
images that do not have cloud-init or really much of anything else. This
is easy to accomplish with debootstrap and rinse.
