title: Docker stopping after first line
body: <p>I have a <code>Dockerfile</code>: </p>
  
  <pre><code>FROM jpetazzo/dind
  ENV debian_frontend noninteractive
  RUN apt-get -y update
  RUN apt-get install -y supervisor
  COPY supervisor.conf /etc/supervisor.conf
  COPY wrapdocker.conf /etc/supervisor/conf.d/wrapdocker.conf
  CMD supervisord -c /etc/supervisor.conf
  </code></pre>
  
  <p>Running it gives me an <code>EOF</code>: </p>
  
  <pre><code>$docker build .
  Sending build context to Docker daemon 2.048 kB
  Sending build context to Docker daemon 
  Step 0 : FROM jpetazzo/dind
  EOF
  </code></pre>
  
  <p>I am on <em>Ubuntu 14.04</em>:</p>
  
  <pre><code>$docker version
  Client version: 1.7.1
  Client API version: 1.19
  Go version (client): go1.4.2
  Git commit (client): 786b29d
  OS/Arch (client): linux/amd64
  Server version: 1.7.1
  Server API version: 1.19
  Go version (server): go1.4.2
  Git commit (server): 786b29d
  OS/Arch (server): linux/amd64
  </code></pre>
  
  <p>Any clue why is there an <code>EOF</code>? </p>
  
  <p>I tried to re-copy the file in another directory, it didn't change anything. Changing <code>FROM jpetazzo/dind</code> to <code>FROM ubuntu</code> does change things.</p>
  
  <p><strong>EDIT</strong>: 
  The logs created during the mistake: </p>
  
  <pre><code>/var/log/upstart$ sudo cat docker.log
