Hi Alexander, thanks for bringing this up. >From your list of problems the only problem which I see is 1st, 2nd and 3rd are solvable even with current implementation.
Also I don't think that we should continue developing our own HW discovery mechanism, we should consider switching to ironic-inspector, and get common discovery system [0]. We need to evaluate it and get a list of features which we may need from it and discuss with ironic team.
