Also there doesn't exist any real-life used OS with Linux and without GNU.
I use and develop EtLinux. It's Linux, Tcl and Tcl scripts. And not necesseraly glibc (libc5 is supported, and soon uclibc). Yes, it's used in real life.
I suspect you'll hate me on the technical level. You are welcome, and you're not alone.
I've never heard someone calling the "GNU/Linux" system "GNU".
I do it pretty often, especially when I talk in public. Despite I run linux+tcl.
Moral: never say never, you got it wrong twice. And you're a little too strong in your posts.
/alessandro, who would better stay off this thread. No, he doesn't use BK.
