I never managed to pull it off, but I tried creating a full live Linux 
environment based on musl, clang, Heirloom Toolchest and OpenBSD/NetBSD 
sources.  The idea was that I wanted to make a "Real Unix" that happened 
to have Linux as its kernel.  (It also would have run the CDE as its 
default desktop.)

One thing I did come up with was, if I were to pull it off, it would be a 
Linux distribution that rightfully could NOT be called, by any means, 
"GNU/Linux" - and some heads would explode.

(I still want to do it, but I remain at a loss as to execution.)

-uso.
