I'm an old BSD head, but the operative word there is "old"... I haven't
used BSD since SunOS 4, so correct my assumptions if I'm wrong.
I assume that BSD has a run-time binary module loading system of some
If so, I don't see why being a DIYer has to enter into the picture at
all. You could quite easily ship a distribution with binary modules that
are covered by the GPL without imposing on the licensing of the overall
There are some caveats:
1. The question of header files is an old one, but we already deal
with this problem cleanly enough throughout the community, so
it's not an issue unique to BSD's kernel (any more than it is to
X.org's display server). For extra-certainty write GPLed
variants of the headers needed for the kernel API.
2. When the user loads these binary modules, they are rendering
their kernel non-shippable (they lose the ability to apply the
GPL to those works, and thus have only fair use to fall back
on). Users almost never care about this.
Now, I don't know what copyright law has to say about "ready to mix"
scenarios like this one, but it seems to me like a very defensible
position. That is, you can always say, "we've never distributed any code
into which GNU licensed code has been mingled."
