this is excellent question. And I was rising similar concerns before. I
believe I managed to get to some compromise how we can achieve such
In Node Profile, you are able to specify HW specs as well as node tags
(both should be already available in Ironic). So if user has Tags well
set up (for example mark desired nodes with specific tag), we should be
able re-use that tag in Node Profile definition of Controller role and
during scheduling process.
I hope that in time we will be able to get to smoother experience ;)
