NixOS Configuration

1. Directory Structure

This repository is structured to support multiple hosts with shared configuration:

• flake.nix: Entry point defining system configurations (homepc and mylaptop).
• nixos/: System-level configurations.
  • common.nix: Shared settings, packages, and users applicable to all hosts.
  • homepc/: Configuration specific to the desktop PC (Nvidia drivers, extra storage).
  • mylaptop/: Configuration specific to the laptop.
• users/vd/: User-specific configuration (Home Manager), including dotfiles (config/).

2. Fresh Installation Guide

After installing NixOS and rebooting into your new system, follow these steps to apply this configuration.

Step 1: Get the Configuration

Install Git (if not already available) and clone this repository:

# Enter a temporary shell with git
nix-shell -p git

# Clone your repository (replace URL with your actual repo)
git clone https://github.com/lvdund/nixos-config /etc/nixos/nixos-config
cd /etc/nixos/nixos-config 

Step 2: Hardware Configuration

Crucial: You must generate the hardware configuration specific to your machine to ensure bootloaders and filesystems are correct.

For Laptop:

nixos-generate-config --show-hardware-config > nixos/mylaptop/hardware-configuration.nix

For Home PC:

nixos-generate-config --show-hardware-config > nixos/homepc/hardware-configuration.nix

Step 3: Apply Configuration

Apply the flake configuration for your specific host:

For Laptop:

sudo nixos-rebuild switch --flake .#mylaptop

For Home PC:

sudo nixos-rebuild switch --flake .#homepc

Update:

nix flake update

3. Git Configuration

Set up your global git identity:

git config --global user.email "lvdund@gmail.com"
git config --global user.name "lvdund"
