</span>I'd really like to get some input from the tripleo folks, because they<br>
were the ones who filed the original bug here and were hit by the<br>
agent NOT reprogramming flows on agent restart. It does seem fairly<br>
obvious that adding an option around this would be a good way forward,<br>
however.<br>

Thanks,<br>
