AT&T seems to be ignoring this.  And they sell X with their products.

If the binaries do't contain GNU libc.a code or bison output, then they
are not covered by the GPL.

Not true. 32V, V6, V7, and up to SVR3 are copyrighted AT&T code.  Anything
that they obtained from outside sources was under license agreements.

But there will still have to be drivers for different video cards, or
massive bloat in the kernel.

Of course.  MSDOS doesn't do multitasking.

If you want UNIX that comes up in X on the console buy SVR4.2.

Real graphics terminals are >$1000.

UNIX is a general purpose operating system.

Get SCO UNIX or SVR4.  Administrative menu systems are provided.

Check out SVR4.2.

I don't seem to have the administrative problems that you describe, and
I have been an administrator for just about every UNIX platform.

Windows 3.x applications are just retreaded DOS versions that require users
to have Windows installed.
