That is not actually where the name "Linux" comes from... http://en.wikipedia.org/wiki/Linux#Naming

There is actually an OS I have used with a similar meaning name however: XINU ("Xinu Is Not Unix"): http://en.wikipedia.org/wiki/Xinu

The most famous (and I believe he original) is GNU's Not Unix.

FYI: XINU was started in 1979 and GNU was in 1983.

There's also XNU, the OS X kernel, which stands for "X is Not Unix", despite the fact that (unlike Linux) OS X has since been Unix certified!
