I just wanted to chime in here to say that although there were several situations where our questions couldn't be answered, we probably wouldn't have made it as far with our testing if it wasn't for the answers that were received from the openstack ironic developers. I should also point out that I've always found the openstack ironic devs to be kind and professional. So be it as it may, it is unfortunate that there are some conflicting priorities but I certainly do not blame the devs.
