How is this part of the code validated? It might capitalize on some type of "trust". Unfortunately … I have no such notion.

I would rather take the path of the "least astonishment", a __consistent__ behavior where we always abide to the configuration files (user level as well as system level). If you want to see every single parameter possibly available to you (based on your rights of course), temporary remove the configuration file. Or we can provide a specific ompi_info option to ignore the configuration files, but not make this the default.
