title: Why can't I create this Route53 CNAME Alias?
body: <p>I'm using <code>fake-domain</code> in place of what we really have.</p>
  <p>This is what I have in R53 right now.</p>
  <pre><code>www.fake-domain.com     CNAME     xxxxxxx.cloudfront.net
  fake-domain.com         MX        {typical MX records}
  fake-domain.com         NS        {aws name servers }
  </code></pre>
  <p>When I try to add a CNAME ALIAS for <code>fake-domain.com</code> to <code>www.fake-domain.com</code> I get the following error:</p>
  <pre><code>InvalidChangeBatch 400: RRSet of type CNAME with DNS name fake-domain.com. is not permitted as it conflicts with other records with the same DNS name in zone fake-domain.com.
  </code></pre>
  <p>What record is it conflicting with? I don't have an <code>A</code> and the only root levels are <code>MX</code> and <code>NS</code>.</p>
