<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Thanks Lucas, Sam, Shivanand and Pavlo for commenting. From the replies, it seems like the original intent of ironic-lib was to solely be used by ironic and ironic-python-agent projects.
But that doesn’t seem to have been communicated properly (because I wasn’t aware of that, nor was Pavlo).<o:p></o:p></span></p>

‘fuel-agent, just so you know. Ironic-lib isn’t quite ready to be used so we cannot guarantee that we won’t break you but we will try our best not to do so’? Or… ?<o:p></o:p></span></p>

<br>
I'm personally fine with that goal, if we as a community agree that in<br>
the soon future of ironic-lib should target a broader audience. The<br>
thing is that I don't think the lib was conceived with that in mind,<br>
we started small (baby-steps) sharing partitioning code from Ironic<br>
and Ironic-Python-Agent, now that it's done we can start working<br>
towards making it a more generic library.<br>
<br>
What I don't think we should do is say that the library's _right now_<br>
ready for it, the interfaces we have at the moment should not be<br>
considered stable, Ironic is very opinionated in many aspects<br>
(specially when partitioning the disk), there's no documentation, no<br>
release notes, etc...<br>
<br>
So, if agreed, let's do it, but let's do it properly.<o:p></o:p></p>
