[Nix-dev] udev-153

[Yury G. Kudryashov]

Hi!

Udev 153 released. New release does not allow us to rewrite firmware search 
path at runtime, but it allows us to specify --with-firmware-
path=path1:path2:... configure option.

I propose to use /var/run/firmware:/root/test-firmware path, and symlink 
/var/run/firmware to /nix/store/hash-firmware. /nix/store/hash-firmware will 
contain symlinks to all files in hardware.firmware directory. This will not 
allow us to modify the set of firmware files symlinked to /var/run/firmware 
after the system is built, but for emergency case we'll have impure 
/root/test-firmware path.

Any objections?
