+description: >
+ 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`.
+
+parameters:
+ dev_rsync_host:

+ dev_rsync_module:
