NixOS Configuration ❄️

Initial setup

1. Install NixOS (or Nix)

   NB! Make sure user- $USER and hostname $HOST match the configuration.

2. Put your SSH key with access to the sops-protected vault and your GitHub account on your host (~/.ssh/id_nix),
   and add it to the ssh agent

   eval $(ssh-agent)
   ssh-add ~/.ssh/id_nix

3. Clone this repository (to path matching $FLAKE)

   git clone [email protected]:runarsf/dotfiles.git ~/.config/nixos
   cd ~/.config/nixos

4. Copy hardware-configuration.nix to the host configuration

   cp /etc/nixos/hardware-configuration.nix ./hosts/${HOST}/hardware-configuration.nix

5. Build and switch

   # NB! If your hostname doesn't match the configured one, temporarily change it in the shell
   ./packages/niks/niks.sh os switch --ask --hostname ${HOST:?} .

6. You should now be able to log in with the same username and the password set in the config (changeme).
   After logging in, make sure to change your password, and check that all the substituters are applied correctly.

   passwd
   
   nix config show | egrep "^substituters"
