> With Docker images, the correct thing to do is to extend FROM the image you want to use, build the whole thing yourself, and then tag and store your image in a container repository. Neither should you rely upon months-old liveCD images.

This should rebuild all. There should be an e.g. `apt-get upgrade -y && rm -rf /var/lib/apt/lists` in there somewhere (because base images are usually not totally current (and neither are install ISOs)).

`docker build --no-cache --pull`

You should check that each Dockerfile extends FROM `tag:latest` or the latest version of the tag that you support. Its' not magical, you do have to work it.

Also, IMHO, Docker SHOULD NOT create another Linux distribution.
