[Nix-dev] hardware.enableAllFirmware doesn't work

[James Cook]

Hello,

When I set hardware.enableAllFirmware = true in nixos, I get a  
collision between firmware-linux-nonfree and linux.  See my  
configuration.nix and transcript at the end.

I am guessing the way to fix this is to set meta.priority on one of  
the two packages, but I don't understand the situation well enough to  
know if that will break anything.

For now, I've worked around the problem by commenting out a few of the  
lines in  
pkgs/os-specific/linux/firmware/firmware-linux-nonfree/default.nix.   
(If it's useful, I found that commenting out linux-nonfree, bnx2,  
iwlwifi and qlogic did the trick.  It works for me because I only need  
the ralink firmware.)

Thanks!
   James
