How I install a new device

  • Install nixos like you normaly would and use initial-config.nix by copying it in /mnt/etc/nixos/configuration.nix before running nixos-install.
  • Reboot in your new, empty nixos system.
  • Use nixops to deploy to this new device using the appropriate section of this readme (or clone this repo and install using nixos-rebuild).

How to clone

Clone this repo using

git clone --recurse-submodules

Update submodules

git submodule update --recursive --remote

Install using with nixos-rebuild

Make sure to symlink the corresponding config:

sudo ln -s ${PWD}/nixos/hosts/<Host>/configuration.nix /etc/nixos
# Be sure the hardware-configuration.nix you are linking is up to date!
# Especially after HDD/SSD change!
sudo ln -s ${PWD}/nixos/hosts/<Host>/hardware-configuration.nix /etc/nixos

When first building, specify config using:

sudo nixos-rebuild -I nixos-config=${PWD}/nixos/hosts/<Host>/configuration.nix -I nixpkgs=${HOME}/.nix-defexpr/channels/nixos/nixpkgs switch

Install using nixops

cd nixops
nixops create home.nix Bur.nix Mimir.nix Skuld.nix -d home
nixops deploy -d home # Deploy to all machines
nixops deploy -d home --include Skuld ## Deploy only to Skuld

nixops destroy -d <uid>
nixops delete -d <uid>

nixops list
nixops info -d home

Notes

Using a software without installing:

nix run nixpkgs.usbutils -c lsusb

Test a package while developing:

nix-env -f ~/src/github.com/m-gregoire/dotfiles-nix/vendor/nixpkgs-m-gregoire -i <PACKAGE>

Theming

Every applications is themed automatically using the defined base16 theme. I manually created the templates in ./home/theme expect for a few were I used base16-builder.
