  This is first boot configuration for development purposes. It allows
  overriding contents of the deployed images via rsync before
  configuration (e.g. Puppet) starts, speeding up the feedback loop
  between making a change and seeing it applied.

  To prepare the host, put something like this to /etc/rsyncd.conf:

      [overcloudsync]
            path = /root/overcloudsync
            comment = overcloud pre-puppet customizations

  Then run `rsync --daemon`.
