my PCs configurations

An attempt to use the NixOS ecosystem to deploy and provision my home machines.

usage

Activate the nix development environment with

nix develop

Make the adjustments you need, then run a check without building anything

task check  # equivalent to nix "flake check --no-build"

Deploy to the machines using task

task viewscreen  # equivalent to "deploy .#viewscreen"

The target node (viewscreen in this case) should already have NixOS installed.

VM testing

to run a vm, use:

task viewscreen-vm

At the first launch, login eith the user root and password "test", then run reboot. This will load the kodi user services and boot kodi at start.

New system

• Install NixOS

• Edit /etc/nixos/configuration.nix to add:

  nix.settings.experimental-features = [ "nix-command" "flakes" ];
  environment.systemPackages = with pkgs; [ git ];

• sudo nixos-rebuild switch

Then you can clone the repo and enter the dev environment with nix develop.

When you're ready, apply the configuration with

sudo nixos-rebuild --flake .#configName switch

where configName is the nixosConfiguration that you want to use on the system.

upgrades

This flake uses nixos-unstable, because I like to live on the bleeding edge!

To properly get the updated packages, do task update once in a while

nixpkgs testing notes

To test a package to be added to nixpkgs, one can use

NIX_PATH=nixpkgs=<local-path> nix-shell --pure -p package-name

For a kodi plugin this would be

NIX_PATH=nixpkgs=<local-path> nix-shell --pure -p "kodi-wayland.withPackages (kp: with kp; [plugin-name])"
kodi
