Whups, I must apologise for being a bit too quick off the mark. I see
the fs module init function is already private. However it's still a bad
idea to throw out the compatibilty check completely, we can just make it
a bit stricter. As I'm about to demonstrate. Feel free to back out my
next commit if you don't like it.
