The upstream bug is closed as working-as-designed, but this is impactful to anything that expects ```df``` to exit 0 as a non-root user.

Maybe statfs() is not implemented, but it would be good to quieten this down (df even does not allow me to ignore it, probably because it looks at statfs to find out fs type, so my fs type ignoring doesn't work).
