My personal opinion is that rebuild is an anti-pattern for cloud, and<br>
should be frozen and deprecated. It does nothing but complicate Nova<br>
and present challenges for scaling.<br>
<br>
That said, if it must stay as a feature, I don't think updating the<br>
user_data should be a priority. At that point, you've basically created an<br>
entirely new server, and you can already do that by creating an entirely<br>
new server.<br>

If you've got a whole heat stack with multiple resources, and you realize that you messed up one thing in the template and one of your servers has the wrong personality/user_data, it can be useful to be able to rebuild that one server without affecting anything else in the stack. That's just a convenience though.<span class="HOEnZb"><font color="#888888"><br>
