- As far as I understood the above article from merlin, AT&T not only claims
- that BSDI has used the trademark "UNIX", but more important, that they had
- taken code from a 'something system' named net-2 from some university, which
- (in AT&T's opinion) might have been rewritten to contain no line that grep
- would match with the original sources, but covers at least the "idea"
- behind UNIX. If I understand this correctly, and AT&T will win, then any
- NIXe or XINe above could be sued. I can imagine an interpretation of what is
- the "idea of UNIX," it might be a lot of things, including
- file system (inodes, hierarchical tree, naming conventions)
- process management (e.g. init, fork, setuid!)
- device driver management (terminal disciplines)
- the set of system and user calls (remember the GETCHAR macro)
- pipelining concept of the shells (in general: user interfacing)
- Any of the derived versions (or reverse engineered or developed from scratch)
- has at least one aspect of UNIX. Even if the programmers haven't even seen
- one byte of AT&T source, there are things that will likely be done the same
- or a similar way, provided the data structures remain "compatible". You may
- #include <stdio.h> in your programs and give your source away, but don't
- dare *) to take a part of /usr/include and put it into your distribution to
- set up a base of compatible definitions....:-(
-
- *) if grep -i AT&T /usr/include/* returns output
-
- Hopefully this will never come true.
