I'd just like to interject...

I'm sitting in a programming course, and eventually the instructor mentions the word Linux. Someone near the back (didn't see who) raises his hand, and when the instructor lets him speak, he proceeds to recite the entire GNU/Linux copypasta. After he's done, the instructor says "Right." and continues lecturing, ignoring the fact that tons of people in the room were either resisting the urge to laugh or in a state of massive confusion.

WHICH ONE OF YOU WAS IT?

GNU was never intended to be UNIX but a system inspired by UNIX. To RMS and GNU, POSIX is a set of recommendations more than anything.

Fun fact: RMS came up with the POSIX name.
