Setup (Overview)

The following is an example procedure for a new setup. Please adapt according to your environment.

1. Clone the repository

git clone https://github.com/... ~/flake
cd ~/flake

Hardware Configuration (/etc/nixos/hardware-configuration.nix)

If NixOS is already installed, copy /etc/nixos/hardware-configuration.nix to sub/hardware-configuration.nix.

sudo cp /etc/nixos/hardware-configuration.nix sub/hardware-configuration.nix 

For a new installation, generate the file using nixos-generate-config in the target environment and adjust as needed.

sudo nixos-generate-config --root /mnt
# Edit before continuing with installation

Secure Boot

For details, see here

sops-nix (Secrets Management)

This repository places secrets/secrets.yaml and secrets/default.nix to be handled by sops-nix.

Please save the keys in .config/sops/age/keys.txt.

# Unencrypted secret.yaml
pass-hash: $6$... # Enter password hash here

Host / User Information in the flake (e.g., hostname / username / git)

home/default.nix is configured to reference specialArgs to pass git user.name / user.email, etc. Either provide values for each host in flake.nix or specify an appropriate target name at runtime.

Excerpt from flake:

# flake.nix (excerpt)
outputs = { inputs, ... }:
  let
    hostname = "nixos";
    system = "x86_64-linux";
    stateVersion = "25.05";
    username = "...";
    gitUsername = "...";
    gitUseremail = "...";
  in
{
  homeConfigurations = {
    ...
  };
};

Applying Configuration

sudo nixos-rebuild switch --flake .#<hostname>
