title: Where to find logs for a cloud-init user-data script?
body: <p>I'm initializing spot instances running a derivative of the standard Ubuntu 13.04 AMI by pasting a shell script into the user-data field.</p>
  
  <p>This works. The script runs. But it's difficult to debug because I can't figure out where the output of the script is being logged, if anywhere.</p>
  
  <p>I've looked in /var/log/cloud-init.log, which seems to contain a bunch of stuff that would be relevant to debugging cloud-init, itself, but nothing about my script. I grepped in /var/log and found nothing.</p>
  
  <p>Is there something special I have to do to turn logging on?</p>
