USER is picked as the user specified by the Docker config or if that is empty is defaulted to root. If the USER is root then HOME is defaulted to /root otherwise it is set to the HOME found when running `env` in a sample of the container. PATH is set to a normal sane default. Any of these environment variables can be overridden in the Dockerfile or using profile parameters at any time. This is just to help users who rely on Docker providing defaults.
