title: Docker shows no containers or images after system reboot
body: <p>Help! I can't get docker to recognize the images and containers it had just a moment ago. After running <code>apt-get update &amp;&amp; apt-get dist-upgrade</code> and rebooting, I see docker reporting no data:</p>
  
  <pre><code>$ docker ps -a
  CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
  
  $ docker images
  REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
  </code></pre>
  
  <p>But the data appears to still be there</p>
  
  <pre><code>$ sudo du -hs /var/lib/docker/*
  8.0K    /var/lib/docker/apparmor
  1.9G    /var/lib/docker/aufs
  136K    /var/lib/docker/containers
  292M    /var/lib/docker/devicemapper
  8.0K    /var/lib/docker/execdriver
  712K    /var/lib/docker/graph
  17M     /var/lib/docker/init
  8.0K    /var/lib/docker/linkgraph.db
  4.0K    /var/lib/docker/repositories-aufs
  4.0K    /var/lib/docker/repositories-devicemapper
  4.0K    /var/lib/docker/volumes
  </code></pre>
  
  <p>Could it be looking in the wrong place for it? Is there some config file that specifies the storage location?</p>
  
  <p>Edit: running <code>docker -d -D</code> reports:</p>
  
  <pre><code>[debug] daemon.go:328 Cannot load container 93092d010a9abe9affc217684782e8b2986e560897eb4527715e9bffe0446136 because it was created with another graph driver.
