Deployment server
Copy the application you want to deploy to the UF in $SPLUNK_HOME/etc/deployment_apps (lets call it foo)

Edit $SPLUNK_HOME/etc/system/local/serverclass.conf to have the following:
  [global]

  [serverClass:mymadeupnamehere]
  whitelist.0 = servername

  [serverClass:mymadeupnamehere:app:foo]
  stateOnClient = enabled
  restartSplunkd = true

Once that's done, run $SPLUNK_HOME/bin/splunk reload deploy-server
   Enter your admin password

When you install the UF, run this command when everything is done:
	$SPLUNK_HOME/bin/splunk set deploy-poll <splunk_server_name_here>:8089 -auth admin:changeme

Thats it!
