title: how to use a private yum repo on amazon-s3 to provision amazon-ec2 instances?
body: <p>My fantasy is to be able to spin up a standard AMI, load a tiny script and end up with a properly configured server instance.</p>
  
  <p>Part of this is that I would like to have a PRIVATE yum repo in S3 that would contain some proprietary code.</p>
  
  <p>It seems that S3 wants you to either be public or use AMZN's own special flavor of authentication.</p>
  
  <p>Is there any way that I can use standard HTTPS + either Basic or Digest auth with S3? I'm talking about direct references to S3, not going through a web-server to get to S3.</p>
  
  <p>If the answer is 'no', has anyone thought about adding AWS Auth support to yum?</p>
