I just wanted the data. That is an exceptionally promising response for my problem :) I did notice that a regdb package exists, and I do have it installed. This possibly explains why that doesn't fix it. I can try and dig into this package to see what’s what — but I’ve no idea of what symlinking might be needed. Any hints off the top of your head would be welcome. If not, I’ll try and look at it later and may have some questions for you… Thanks!

Ah, no, that shouldn’t be the problem at least. The kernel is whatever’s current on NixOS — 4.4.something? — and the hardware is over a year old. It’s a QCA9890 chip. The early firmware for these was actually little unstable for me (I had problems with that other machine last year when I first got it), but has also been good since around the 4.3 era at least.

Oh, oh! One for the group:
I notice that the crda package has a udev rule in it:
/nix/store/6nzijs5fiwsm4hzpvvfyxkhb17gxdwwc-crda-3.18/lib/udev/rules.d/85-regulatory.rules
but after installation this rule has not made it into my
/run/current-system/sw/lib/udev/rules.d/ folder (I think it needs to be there
for it to work, right?)
So, what can I override in the crda package derivation (or whatever) to make
this symlink happen? Nix is frustrating sometimes — a simple ln -s is
disallowed! :)
After some poking, I’ve found the services.udev.extraRules key, and added the
text of the rules file to that in my configuration.nix, as
services = {
udev = {
extraRules = "KERNEL=='regulatory*', ACTION=='change',
SUBSYSTEM=='platform',
RUN+='/nix/store/6nzijs5fiwsm4hzpvvfyxkhb17gxdwwc-crda-3.18/bin/crda'";
};
…
but that doesn’t seem to help either.
So close! Possibly…
Any thoughts?

Re: [Nix-dev] Wifi DFS configuration/reg database (was Re: Specifying particular firmware)
Alright, folks, I think I’ve figured it out.
The crda package has the udev rule, but doesn’t add itself to the
services.udev.packages list.
Adding simply:
services = {
udev = {
packages = [ pkgs.crda ];
};
…
};
to my configuration.nix got it working. Win! Such a tiny fix.
I am still figuring out how these things work in nixland, but I see a couple of
others, such as pkgs/os-specific/linux/rfkill/udev.nix, where there is a
comment explaining you should do basically this to enable it. Should such a
comment be added to the crda package? If so, should I file this as a GitHub
issue?
Ta,
Matt
