Actually, about two years ago a large company I previously worked at performed a formal legal review of the GPL, as part of a due-dilligence review whether to use Linux rather than a commercial OS in some of its products.
One of the points raised was that the license clarification for user programs was added by Linus to copying.txt well before most other authors started working on the kernel - it can be traced back to a nascent version of Linux to which most everyone else then submitted their code into later on.
It was the opinion of the IPR lawyer reviewing the license that the "user program" clarification is therefore a part of the core Linux license, is legally binding and applies to all such subsequent code submitted by other authors.
It's a subtle point, but I thought it would be worth a mention. Ultimately, it would be for the courts to decide I guess, if any GPL copyright dispute ever makes it that far.
Just goes to show that some companies are concerned about working effectively with the GPL - it took several weeks of highly paid IPR lawyers to formate a policy document which they considered acceptable use. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
