Re: @ Kubla Cant -- Not too sure
"Funny, all the copies of unix around here came with a generic GUI."
ITYF there will be more than one installed so the "generic" one you're talking about is whatever WM is kicked off in the xinitrc file. If you had a clue you might realise this.
"Even Linus T doesn't think that unix == the kernel."
It isn't. Its the kernel + filesystem + all the admin & userland tools and sub systems NOT including graphics. The majority of the worlds linux/unix systems spend their lives as headless servers or embedded devices - not desktop PCs. They don't need graphics. Something MS only cottoned on to in the last few years. But then their "servers" have always been a bit Fischer Price compared to unix and mainframe systems to be frank.
