Installation

Installing on the target machine

Boot the target machine from NixOS ISO and run the following command:

sudo nixos-generate-config

Prepare host configuration based on the generated /etc/nixos/hardware-configuration.nix file. Put it in hosts/$HOST directory in the repository, where $HOST is the name of the host device of your choice. When you are ready, commit the changes to the repository.

Put the age private keys on the target machine either in ~/.config/sops/age/keys.txt or somewhere else with SOPS_AGE_KEY_FILE environment variable set. The installation script will copy the keys to persistent storage.

Change the HOST variable to the name of the host configuration you want to install and run:

sudo nix --experimental-features 'nix-command flakes' run "github:spietras/systems#${HOST}-install-script"

and then reboot the machine.
