[arch-dev-public] RFC: crda PKBUILD

[Thomas Bächler]

Linux 2.6.28 will support a new wireless regulatory domain infrastructure. Instead of the limited number of hardcoded regulatory domains in cfg80211 (EU, JP, US), there will be a userspace daemon that manages regulatory domains. We could still enable the "old" regulatory domain in the kernel. However, I would like to disable it, so kernel26 will have dependency (or optdependency) on crda (as would compat-wireless, if someone builds it with the new regulatory framework enabled).

I am attaching the PKGBUILD for crda.

The package includes the crda and regdbdump binaries, as well as a binary regulatory.bin database and a udev rule. John Linville's RSA public key is hardcoded in both crda and regdbdump, so they will only accept regulatory.bin files signed by him. (The build system allows to include other public keys and the data to build the regulatory.bin is publicly available.)
