title: How to remove docker container even if root filesystem does not exists?
body: <p>I have one container that is <code>dead</code>, but I can't remove it, as you can see below.</p>
  
  <p>How can I remove it? Or how can I clean my system manually to remove it?</p>
  
  <pre><code>:~$ docker ps -a
  CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES

  :~$ docker rm --force 78b0dcaffa89
