Setup

First Install

For your first install / inital setup, please refer to README-first-time-install.md for instructions.

Secrets

Information regarding secrets e.g. root password and so on, can be found here: README-secrets.md.

Usage

Update pkgs e.g. apt update

Sometimes you need to update the flake.lock file to get new versions of programs. The command to update your pkgs versions is nix flake update, but the Makefile provided with this repository allows you to also use make update

Install pkgs e.g. apt upgrade / apt install

To then install the new pkgs that have been configured in the flake.lock file you need to use nixos-rebuild switch --flake . --use-remote-sudo. The Makefile also provides a simpler command make deploy and a debug version of that named make debug.
