He confirms that the Linux Kernel Personality did indeed include Linux kernel code, and as a result, both UnixWare 7.1.2 and 7.1.3 included Linux kernel code until May of 2003.
While Hughes testifies that in addition to the obvious candidates (Caldera's Linux distributions), two releases of UnixWare included the Linux kernel in some way, as part of the LKP -- and of course, such inclusion would have to be under the GPL -- yet the question that is left unanswered, tantalizingly, by the deposition is this: in what way was the Linux kernel "included" in LKP? Did the UnixWare kernel somehow make use of the Linux kernel binary? If so, how -- and would the use be intimate enough to have created a "work based on the program" as the GPL puts it? If not, how was the kernel "included"? Was kernel source code reused in the UnixWare kernel, as one anonymous source claimed to eWeek's Peter Galli long ago? We don't have totally firm answers to these questions from this deposition alone, but IBM probably does, and we're definitely getting warmer. And more and more, it looks like SCO's goose is cooked.
