A Linux distribution is a mere aggregation according to FSF legal.

To Bill Unruh and other interested parties:

I've finally received a response to the series of questions I posted to
the Free Software Foundation's legal people at licensing@fsf.org, and I
have been given formal permission to post the e-mail in question here
on USENET. Maybe this will spur some discussion.

I've included the headers to provide some context/validation.

Hi Richard,

Thanks for writing!

Linux distributions are mere aggregrations of various pieces of Free
Software and, in some cases, proprietary software.

Only the portions of the distribution that form derivative works with
GPL'd components must be GPL'd.

However, the work as a whole cannot be licensed under another license,
nor can the terms and conditions of the GPL be restricted by another
license.

Our FAQ does address this:
http://www.gnu.org/licenses/gpl-faq.html#MereAggregation

If you think this isn't clear, can you suggest a clarification?

Well, the whole thing isn't one "work" under copyright law, but if you
s/WORK/distribution/, that's right.

Right.

Yes.

OK, I'll open an internal ticket on this.
