I'm from the Mogan team, we chose the same keyward 'baremetal' when implementing a OSC plugin [1]. As we think the baremetal command is representative of a baremetal resource, not a service, so it makes sense for different projects to share the top level resource
name that OpenStack can provide.<u></u><u></u></p>

<p class="MsoNormal" style="margin-bottom:12pt"><br>
We do not "own" the word "baremetal", so nothing prevents you from using it. However, in my experience:<br>
1. This does confuse users, as they expect "openstack baremetal" to be a prefix belonging to Ironic.<br>
2. Collisions may happen. We had two collisions with TripleO already, one resulted in us killing a TripleO command abruptly.<u></u><u></u></p>

Ironic does not have any notion of either of these, so it should be fine.<br>
<br>
I'm still a bit on a -1 side because of potential users confusion. I wonder how can we send a message across that prefixes do not designate a specific project, but are rather just part of a "sentence". I'm specifically worried about confusing "baremetal server"
of Mogan with "baremetal node" of Ironic. For many people these can be synonyms.<u></u><u></u></p>
