Yeah, exactly :-(.  Other than finding a MAC address, it doesn't seem
like there's much there, and we've spent an awful lot of work on
supporting N different libraries for this.

implementation seems to be inside the kernel, so that's not likely
to be helpful, but the other two must be in userspace.
