Way to automatically detect device and apply correct fixes

[mkg20001]

Don't know if it's possible but there should be a way to do something like <nixos-hardware/auto-detect> which would automatically include the right config for the device, which could enable including the right config in an automated fashion.

Otherwise a tool that just returns the right path or nothing if no hardware-quirk conf is needed would be cool

Needing this for scripting purposes

When doing inxi -v7 it spits out, among other things:

Machine:
  Type: Laptop System: LENOVO product: 4334 v: Lenovo G570 

Based on those (wherever it got those from) the device detection could work

Seems to be /sys/class/dmi/id/product_*

$ tail /sys/class/dmi/id/product_*
==> /sys/class/dmi/id/product_family <==
IDEAPAD

==> /sys/class/dmi/id/product_name <==
4334                            
tail: '/sys/class/dmi/id/product_serial' kann nicht zum Lesen geöffnet werden: Permission denied

==> /sys/class/dmi/id/product_sku <==
HuronRiver_CRB
tail: '/sys/class/dmi/id/product_uuid' kann nicht zum Lesen geöffnet werden: Permission denied

==> /sys/class/dmi/id/product_version <==
Lenovo G570

(See #49, with similar goals.)

Nix itself will not be able to take a peek at the system, especially given the purity focus flakes is having. This, though, could happen in a "nixos-hardware-detect" kind of script.

This issue has been mentioned on NixOS Discourse. There might be relevant details there:

Is there any news on that? I think it could be very interesting to have at least a script that proposes some configuration for the hardware. For example, if I have this graphics card, then I should enable this module... Ubuntu was doing something similar at some point, not sure if we can get inspired by that. But at least a minimal script that handles some basic configuration would be nice.

I just discovered nixos-hardware, and I think it's a great project, but I doubt that all computers will enter in that table (mine is not for example), so a more generic solution could be nice as well. For example it seems that intel usually uses this configuration, does that mean that I should use that as soon as I have a Intel computer? If there are some commands that can be run to check if I need i915 kernel module, then it could be nice to pack it in a script.

NixOS has a way to do this through nixos-generate-config. There's further discussion here: https://github.com/NixOS/rfcs/pull/70
