# This generates a Docker/OCI image that looks a lot like an
# Atomic Host ostree (in terms of filesystem layout).
#
# See https://github.com/ostreedev/ostree-releng-scripts/pull/14
# and in particular its `skopeo2ostree` tool.
#
# One could in theory actually combine the whole chain of
# `docker build` on this Dockerfile with `skopeo2ostree`
# and then `rpm-ostree ex commit2jigdo`.
