Linus's explanation in the Linux "COPYING" file is unclear. In the relevant
sentence he states that "this copyright does *not* cover user programs that
use kernel services by normal system calls", which might be construed as
meaning that the Kernel copyright does not regard user programs as ever
being part of a "work based on the Program", or it could mean that no
copyright is claimed over user programs just because they make system
calls, or both, (these being two different things, one being the scope of
a collective work, the other being the copyright on the user program).
But then he goes on to say " - this is merely considered normal use of the
kernel, and does *not* fall under the heading of "derived work".", thereby
suggesting that the disclaimer is intended to have the narrower second meaning,
not the first. If this is the case, then my argument would apply to Kernel
code and user code, if they are presented as a collective work, supplied by
a single party.
