Comment 11 for bug 1775782

@Abhishek: I don't doubt that you tested this, I thought it was working, too. I think it has to be tested in a completely clean environment (which is why I didn't mess with trying both --config-file and --config-dir in the exec statement in the systemd file). There also could be an element of randomness depending on the order oslo.config reads the files, though it was systematically bringing up the API on the registry port in my environment.
