OK, in that case here is my first shot at this.


Tim -- notice both packages have a Replaces: wireless-crda. If debian
upstreams both packages then I think it would be good to separate the
packages as I am recommending for integration on Debian and for Ubuntu
to also use the same debian packages as debian. I think this would
mean also having the new Ubuntu kernels depend on these new packages
instead of the old wireless-crda.

The package is very simple, I took what I could from Kel's work but
did leave in the signature check stuff, used openssl and also just
used cdbs. The wireless-regdb does not change *that* often so I do not
expect debian itself to need a custom regulatory database to be
automatically built and propagated so I left all the watch stuff out
and can do manual updates for now, I can commit to that for now. If
that is a requirement however, I am not that familiar with new package
policies and am unclear how to do that. I would prefer if we can get
something started and uploaded for now which at least meets the
requirements for integration into an eventual stable release, but
that's just me.

Please review and let me know what you think.

Also, a slightly related change is to change the kernel configuration
to disable CONFIG_WIRELESS_OLD_REGULATORY. Can someone take care of
that on the debian kernel side? We don't necessarily need to wait for
crda/wireless-regdb to do that.

No problem.

Sure, we'll have to write something up for that on the wiki.

Right, I believe this ought to be the way things change for regulatory
compliance in the future too.
