nix-config

Install from ISO

The install of these configurations is best done from a fresh, minimal NixOS install. For this, download and flash the ISO onto a USB stick and boot from it.

The nix-config contains a few helpful commands that aid in the CLI-based installation. Thus, clone the repository with

git clone https://github.com/phdenzel/nix-config.git

Then, you can inspect the justfile for the commands necessary for a proper installation.

cd nix-config
nix-shell -p just
just iso-install <my-machine>

where <my-machine> has to be replaced with the name of an implemented host. So far,

• idun
• phinix

are implemented.

This will install and build a minimal fresh version of NixOS.

Install on NixOS

Log in to a NixOS installation as root and clone the repository once more:

git clone https://github.com/phdenzel/nix-config.git
cd nix-config

Then, make sure you have copied an authorized AGE key onto the machine to

~/.config/sops/age/keys.txt

To derive and register a new authorized key from the host SSH key

just host-age-key

Once all preparations are done, run

sudo nixos-rebuild switch --flake .#<my-machine>

where <my-machine> has to be replaced with the name of an implemented host.

Alternatively, you can run the shorthand

just rbs <my-machine>

Modify and adapt further configuration as needed.
