It seems to use the same BSD statfs way. Well, it can exercise getattrlist(), at least. Also, my point was that some of the information one might be interested in from the mount flags could be available in different forms from the other APIs. It depends on what you're actually looking for. And FSMegaInfo is a very convenient tool for see exactly what those other APIs can provide.
