<p dir="ltr">I must agree with Martin here. <br>
In addition, I think the benefit here is low, and the efforts it will require and the risks are high. Upgrade issues? Compatibility ones? Effect on engine features such as host upgrade manager, different provisioning products that might rely on that such as puppet recipes, ansible modules, or others... <br>
(can't say all mentioned stuff are relevant, and I guess there might be more implications than I've described). </p>
<p dir="ltr">IMHO, we should spend our time improving our project rather than spend a lot of developers, testers and integration people on these kind of tasks. </p>
<p dir="ltr">In addition, bootstrapping of hosts doesn't require manual installation of VDSM, and as of 3.6 neither does upgrade, so most users shouldn't know and care what VDSM is.</p>
