NixOS and home-manager configurations

This repo holds my nix configurations.

Configurations

The rebuild script takes care of applying the hardware-configuration.nix without checking it in to the repo. Also handles formatting nix files and auto-generating a commit message. Inspired by No Boilerplate's rebuild script.

Flakes

The configurations use nix flakes.

I followed this guide to get NixOS and home-manager running using a flake.

Uses my neovim config as an input.

Hosts

Currently running on these hosts:

  • PC with NixOS unstable (also uses home-manager unstable)
  • MacBook with home-manager (on MacOS)

Coming Soon(ish?)

  • Configurable home-manager. This will allow me to use this same repo for my Mac's home-manager config as well. The goal is to keep linux-specific and darwin-specific configs separate while sharing as much nix code as possible between them.
  • nix-darwin set up.

NixOS set up

Starting from a fresh NixOS set up, this describes the steps needed to get a fully working set up.

  • Enable flakes support: add the following snippet to /etc/nixos/configuration.nix: 
    nix.settings.experimental-features = [ "nix-command" "flakes" ];
  • Get git and an editor: either add it to /etc/nixos/configuration.nix or use nix-shell -p git neovim
  • Clone this repo: cd && git clone https://github.com/Samyak2/nixos.git
  • Switch: sudo nixos-rebuild switch --flake .
  • Reboot
  • Set up ssh and gpg keys

MacOS set up

Starting from a fresh Mac OS installation, this describes the steps needed to get a fully working set up.

  • Install nix using the determinate systems installer
  • TODO: xcode CLI tools are needed?
  • Clone this repo: cd && git clone https://github.com/Samyak2/nixos.git
  • Get a shell with home-manager: nix-shell -p home-manager
  • Switch: home-manager switch --flake .
  • Set up ssh and gpg keys

Set up ssh and gpg keys

  • Generate and add a gpg key:
    • gpg --full-generate-key
    • (9) ECC (sign and encrypt) *default*
    • (1) Curve 25519 *default*
    • Key is valid for? (0) 6m
    • Use gpg --list-secret-keys --keyid-format=long and copy the ID (the text after ed25519/)
    • gpg --armor --export <key-id>
    • Add gpg key to GitHub: https://github.com/settings/keys
  • Generate and add an ssh key:
