This soap opera is getting painfully comical. Now it turns out that there's a slight, nonzero possibility that SCO is initiating a heavy-handed lawsuit based on code Caldera copied from Linux into SCO Unix. Furthermore, the act that is causing SCO to sue IBM on trade secret violations may actually be SCO's GPL violation:
A source close to SCO, who spoke on condition of anonymity, told eWEEK that parts of the Linux kernel code were copied into the Unix System V source tree by former or current SCO employees.What's next? Revelations that the code in question came from *BSD, which makes it free for anyone to use?[...]
The source, who has seen both the Unix System V source code and the Linux source code and who assisted with a SCO project to bring the two kernels closer together, said that SCO "basically re-implemented the Linux kernel with functions available in the Unix kernel to build what is now known as the Linux Kernel Personality (LKP) in SCO Unix."
