Hosts

The flake builds two NixOS hosts. Both import conf/shared.nix and then add machine-specific options from conf/machines/{machine}/configuration.nix.

nix-haxorus

ThinkPad configuration.

Files:

• conf/machines/thinkpad/configuration.nix
• conf/machines/thinkpad/hardware-configuration.nix

Flake target:

sudo nixos-rebuild test --flake .#nix-haxorus
sudo nixos-rebuild switch --flake .#nix-haxorus

Host-specific settings:

• hostname: nix-haxorus
• thermal daemon enabled
• TLP enabled
• power-profiles-daemon disabled
• default TLP mode set to battery
• CPU governor set to performance on AC and powersave on battery
• fingerprint daemon enabled

owais-nix-hp

HP configuration.

Files:

• conf/machines/hp/configuration.nix
• conf/machines/hp/hardware-configuration.nix

Flake target:

sudo nixos-rebuild test --flake .#owais-nix-hp
sudo nixos-rebuild switch --flake .#owais-nix-hp

Host-specific settings:

• hostname: owais-nix-hp

The HP file currently only imports shared config and hardware config.

Add another host

1. Create conf/machines/{machine}/.

2. Generate hardware config:

   sudo nixos-generate-config --show-hardware-config \
     > conf/machines/{machine}/hardware-configuration.nix
   

3. Add configuration.nix that imports hardware config and (import ../../shared.nix).nixos.

4. Set networking.hostName.

5. Add a nixosConfigurations.{hostname} entry in flake.nix.

6. Test before switching:

   sudo nixos-rebuild test --flake .#{hostname}
