When I boot from the iso, the following commands give the following result which I do not understand: docker command: works user-docker: FATA[0000] remove /var/lib/rancher/engine/docker: permission denied [rancher@rancher ~]$ sudo user-docker FATA[0000] open /engine: no such file or directory [rancher@rancher ~]$ docker -bash: /bin/docker: No such file or directory system-docker: works perfectly SO, I don’t get it: if you try running user-docker it will remove your ability to run the “normal” docker and won’t run anyway but once you run system-docker you still won’t be able to run user-docker? ---

`user-docker` is a command designed to be used behind the scenes and not for general usage. It’ll be hidden in v0.8.0 and future releases. ---
