[RFH] Debian 2.6.32 CONFIG_WIRELESS_OLD_REGULATORY, wireless-regdb and crda

Adding debian-devel and debian-mentors.

As per Paul Wise' advice I'd like to request for help with the
crda/wireless-regdb package for Debian for the next release of Debian.
I am the upstream crda maintainer and John Linville is the upstream
wireless-regdb maintainer. Kel Modderman has already done most work
required for the Debian package, if not all. What we now need is some
Debian Developer to be willing to either upload the package as-is, or
some help from some experienced package maintainers to address a few
items. I should note Paul Wise has offered sponsorship for this
package so I think we are on the last track to getting this package
finalized and/or uploaded but he just noted a few changes required.

Summary of review with Paul Wise:

  * Package could likely be uploaded into Debian as-is, just requires
someone comfortable with it

  * We need more help with thepkg-wpa-devel group

  * Sponsorship available by Paul Wise given a few change below are made:
      o Modify the Makefile to add a 'make dist' to generate a
ChangeLog using git2cl [1]
         and NEWS based on crda and wireless-regdb upstream git

Paul I'm not familiar with the sponsorship process on Debian, does
this mean if the above is address you would be wiling to upload the
final package yourself? Or does this have other implications?

I address some of Paul's own comments below. If you would like to read
the original thread you can refer to the pkg-wpa-devel package list.

If anyone has any questions please let me know.

Yeah hope

No, I meant that some distributions won't run make at all. Those who
do will always have something done if you don't yet have a key built
for you. By default the regulatory.bin is signed with this key. You
will re-sign the file if db.txt changes.

Fedora does build stuff so they just go with the defaults. Ubuntu just
ships the provided regulatory.bin, they do not build anything, the
package is very simple for the binary regulatory database as you
really only need to build if you have policies which require this (the
content would be the same except the signature), or you want to change
the database yourself.

Think it is a false positive.

Thanks, I understand now. I just downloaded git2cl:


I'll include some ChangeLog for the next release. Its up to John if he
wants to use that as well, he maintains wireless-regdb while I
maintain crda. The current Debian package puts these two together
though so something custom is required anyway for now.

OK great thanks.

Great hope this means this will give us time to get this ironed out
for inclusion.
