The use case is being able to run all the <i>zillions</i> of existing Ubuntu-based Docker images on Windows Server.  If the Ubuntu-using Dockerfile is mostly made up of &#x27;RUN apt-get install&#x27; commands along with a few commands like `RUN cd &#x2F;tmp; wget <a href="https:&#x2F;&#x2F;ourhost.foo&#x2F;some.config" rel="nofollow">https:&#x2F;&#x2F;ourhost.foo&#x2F;some.config</a> -O &#x2F;etc&#x2F;someapp&#x2F;some.config` then it just might work with the Ubuntu-on-Windows thing.
