NixOS profiles covering hardware quirks.

Add a new channel:

$ sudo nix-channel --add https://github.com/NixOS/nixos-hardware/archive/master.tar.gz nixos-hardware
$ sudo nix-channel --update nixos-hardware

Then add an appropriate profile path to imports in /etc/nixos/configuration.nix. Currently available profiles:

Model	Path
Acer Aspire 4810T	<nixos-hardware/acer/aspire/4810t>
Acer C720	<nixos-hardware/acer/c720>
Airis N990	<nixos-hardware/airis/n990>
Apple MacBook Pro 10,1	<nixos-hardware/apple/macbook-pro/10-1>
Apple MacBook Pro 12,1	<nixos-hardware/apple/macbook-pro/12-1>
Dell XPS 15 9550	<nixos-hardware/dell/xps/15-9550>
Lenovo IdeaPad Z510	<nixos-hardware/lenovo/ideapad/z510>
Lenovo ThinkPad T410	<nixos-hardware/lenovo/thinkpad/t410>
Lenovo ThinkPad T440p	<nixos-hardware/lenovo/thinkpad/t440p>
Lenovo ThinkPad T460s	<nixos-hardware/lenovo/thinkpad/t460s>
Lenovo ThinkPad X140e	<nixos-hardware/lenovo/thinkpad/x140e>
Lenovo ThinkPad X220	<nixos-hardware/lenovo/thinkpad/x220>
Microsoft Surface Pro 3	<nixos-hardware/microsoft/surface-pro/3>
Raspberry Pi 2	<nixos-hardware/raspberry-pi/2>
Samsung Series 9 NP900X3C	<nixos-hardware/samsung/np900x3c>
Supermicro A1SRi-2758F	<nixos-hardware/supermicro/a1sri-2758f>
Supermicro X10SLL-F	<nixos-hardware/supermicro/x10sll-f>

For example, to enable ThinkPad X220 profile, your imports should look like:

imports = [ <nixos-hardware/lenovo/thinkpad/x220> ./hardware-configuration.nix ];

Profiles should favor usability and stability, so performance hacks should be activated by an additional NixOS option or conservative and performance configs can be declared in seperate profiles.

Because profiles can only be tested with the appropriate hardware, quality assurance is up to you.
