In my humble-but-correct opinion*, Linux and its origins fit into the general topic of UNIX history just as well as those of Research UNIX or BSD or SVr4.2.2.2.2.2.2.2 or SunOS or IRIX or Ultrix or Tru64-compaqted-HPSauce or whatever. It all stems from the same roots, despite the protestations of purists from all sides. Warren gets final say, of course, but to encourage him I will say: Ploooogie!
