Unlike the entries in `/etc/hosts`, environment-variables for linked containers are not automatically updated if the linked container is restarted. This adds a note to the documentation in; https://docs.docker.com/userguide/dockerlinks/#environment-variables and https://docs.docker.com/reference/run/#env-environment-variables To make users aware that this is the case and recommends them to use the `/etc/hosts` entries in stead. I added this change because users were expecting environment variables to be updated automatically as well (https://github.com/docker/docker/issues/10164).
