title: Why does docker mount a file with a numeric value as a directory?
body: <p>Running a <code>docker run</code> command with:</p>
  
  <pre><code>-v=/path/to/file/name0.conf:/etc/name.conf
  </code></pre>
  
  <p>was resulting in the docker container not being started:</p>
  
  <pre><code>docker: Error response from daemon: Cannot start container &lt;hash&gt;: [9] System error: not a directory.
  </code></pre>
  
  <p>Why is this file not mounting in Docker? </p>
  
  <p>I can make the name nameA.conf and mount it fine. The file nameA.conf and name0.conf are identical (verified with <code>diff</code>), have the same rights (verified with <code>ls -l</code>).</p>
