Using our Docker/dind application the beta instance, I can pull and run, but I can't build (e.g., cowsay example). It fails during apt-get update – which fails from inside a basic docker run. I am however able to build/apt-get with the new Cloud9 docker container. This may have something to do with how we construct the different Dind containers.

So, either we remove the old wetty/dind service and default to Cloud9 Docker for the tutorial, or we fix this in the dind container.
