Hi, I'd like to use obuilder_spec to describe an image and be able to locally build it using Current_docker.

For now it's complicated because Current_docker.Default.build expects a ('Contents of Dockerfile.t), but Obuilder_spec.Docker.dockerfile_of_spec returns the dockerfile as a string. So I actually have to write down the content to a file using Current_fs.save and then use 'File of Fpath.t in the current_docker build.

Do you think it would be possible to have the conversion from an obuilder spec to a Dockerfile.t to simplify the process ?
