See this paragraph in the GPL:
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
Putting GPL and non-GPL code in the same iso image looks to me like an
example of mere aggregation, so my guess is that even if Libranet's
current wording violates the GPL, they could achieve the same effect
by adopting a different wording: instead of saying that "The Libranet
iso image is copyright 2000 Libra Computer Systems Ltd" and that they
are not giving permission to do XYZ, they could instead say that the
Libranet iso image contains material that is copyright 2000 Libra
Computer Systems Ltd and that they are not giving permission to do
However, this change may be unnecessary. It's highly probably that
Libranet would have a valid copyright over the iso image even if the
image contained only GPL programs, as the selection and arrangement
could itself constitute a work to which copyright is applicable.
However, I'm not a lawyer.
By the way, I think it would be bad for Debian if what Libranet is
doing were to turn out to be illegal.
