# The reason we have to do it this way is that we can't mount an image during build.
# Mounting the image at runtime is allowed (when run with --privileged), so we do
# that and then defer to entrypoint.sh which is from https://github.com/ehough/docker-nfs-server
# and takes care of the actual NFS serving
