question: device-tree-overlay suported?

[Stunkymonkey]

Is your feature question request related to a problem? Please describe.

I just noticed this no longer works for me in nixos-hardware (i know other repo and not your issue):

  hardware = {
    raspberry-pi."4".leds = {
      eth.disable = true;
      act.disable = true;
      pwr.disable = true;
    };
  };

in nixos-hardware there are other parts configuring LEDs, ... for example. is this something that will be replaced by nixos-facter?

because i can not really see how this will be implemented.

Describe the solution you'd like

just an answer 😉

Describe alternatives you've considered

is this something that will remain in nixos-hardware?

That's a good question. Something I wanted to have is automatically loading the right nixos-hardware module using nixos-facter. On x86 we can use the sku numbers and on Linux it would be device tree. I think for more generic hardware that can be found in one or more devices it would make sense to have nixos-facter modules, whereas in nixos-hardware we also have a number of quirks that are highly model specific. So the end-game would be something where many things that are provided manually in nixos-hardware is included automatically and only stuff where heuristics failed needs to be fixed by nixos-hardware.
