This is mainly/initially to support use of Cirrus-CI in https://github.com/containers/buildah since that setup re-uses the VM images from this project. However, it also opens doors here, if libpod ever needs/wants to do things with a dedicated storage device and/or storage-drivers. Signed-off-by: Chris Evich <cevich@redhat.com>
