Dotfiles with Nix

This repository contains my personal configuration files (dotfiles) managed using Nix Flakes. It supports both macOS and NixOS on a WSL2 subsystem in Windows.

⚠️ It's important to understand what the code does before applying to your own system. It has a learning curve to use Nix, take action rigorously!

Features

• Nix Flakes: Manage dependencies and configurations.
• Cross-Platform: Works on macOS and NixOS (WSL2).
• Custom Modules: Modular configuration for easy customization.

Installation

1. Prerequistes:

   • Nix: Use this 3rd party script (recommended) or follow the official Nix installation guide.
   • Home manager: Github repo
   • Nix-darwin (for MacOS): Github repo

2. Clone the Repository:

   git clone https://github.com/xixiaofinland/dotfiles-nix.git ~/dotfiles-nix
   cd ~/dotfiles-nix

3. Activate Flakes:

   • If you used the official Nix installation guide, make sure to enable flakes by adding experimental-features = nix-command flakes to your ~/.config/nix/nix.conf, or whatever way to enable the the flake feature.
   • If you used the 3rd party script, flake should have been auto-enabled for you.

4. Commands:

   Nix update with flake.lock:

   nix flake update # update everything
   nix flake lock --update-input sfdx-nix --update-input rust-overlay # update only specified packages
   

   In NixOS:

   sudo nixos-rebuild switch --flake ~/dotfiles-nix/
   sudo nix-env --list-generations --profile /nix/var/nix/profiles/system
   sudo nix-env --switch-generation 93 --profile /nix/var/nix/profiles/system

   In MacOS:

   nix run nix-darwin -- switch --flake ~/dotfiles-nix/
   darwin-rebuild --list-generations # list previous builds
   darwin-rebuild switch --switch-generation 124 # roll back to the number 124 from the above list

Structure

• flake.nix: Main entry point for Nix Flake.
• modules/: Contains custom Nix modules.
• dotfiles/: Holds individual dotfiles for various applications.

Debug

In MacOS Darwin

"warning: ignoring the client-specified setting 'trusted-public-keys', because it is a restricted setting and you are not a trusted user"

Make sure /etc/nix/nix.conf has correct content especially no duplicate entries, for example:

trusted-users = root xixiao
trusted-substituters = https://xixiaofinland.cachix.org https://cachix.cachix.org https://nixpkgs.cachix.org
trusted-public-keys = xixiaofinland.cachix.org-1:GORHf4APYS9F3nxMQRMGGSah0+JC5btI5I3CKYfKayc= cachix.cachix.org-1:eWNHQldwUO7G2VkjpnjDbWwy4KQ/HNxht7H4SSoMckM= nixpkgs.cachix.org-1:q91R6hxbwFvDqTSDKwDAV4T5PxqXGxswD8vhONFMeOE= cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=

NixOS in Win WSL2

Sometimes the sudo permission is gone mysteriously

• wsl --list --verbose
• wsl -d NixOS -u root
• ls -l /run/wrappers/bin/sudo
• sudo chmod 4755 /run/wrappers/bin/sudo
