Umm, this discussion has gone on quite long enough, thank you very much.
It doesn't really _matter_ what people call Linux, as long as credit is given where credit is due (on both sides). Personally, I'll very much continue to call it "Linux", but there have already been distributions that call it "Linux Pro(tm)" etc, which I don't find all that surprising..
The GNU people tried calling it GNU/Linux, and that's ok. It's certainly no worse a name than "Linux Pro" or "Red Hat Linux" or "Slackware Linux" (the last two are often just called "Red Hat" and "Slackware" when talking among Linux people, so there the "Linux" part has fallen off altogether).
Lignux is just a punny name - I think Linux/GNU or GNU/Linux is a bit more "professional" myself, but I'm not going to get gray hairs about this.
Much worse than the strange name is all the silly newsgroup and email activity this has resulted in. It's not as if the FSF unilaterally changed the name of the OS - they just changed the name of their "distribution" (well, it seems it's currently just GNU emacs for Linux, but maybe this will be a trend).
Btw, I've often been irritated by the "unknown" in the gcc setups for Linux, and I'd much rather see a gcc calling itself "i586-gnu-linux" than "i586-unknown-linux" any day (but I have to admit that either is preferable to "lignux" in this context ;-).
