System Configuration and Management

Just another personalized take on how to manage systems, configurations, and shared tooling using Nix. The main purpose is to decouple system profiles into re-usable flake packages that you can install or use.

Prerequisites

• Install Nix in Daemon Mode: https://nixos.org/download
• Register the repository:

  sudo nix registry add adaliszk github:adaliszk/system

Setup

Main assumption for systems is that they are from scratch without GUI by default. The goal with that is to leave the user-facing side to Nix, and keep the core system packages focused around running the kernel and absolutely necessary services.

To kick off the global Nix configuration, run:

sudo nix profile add adaliszk

After these essentials are installed, you can use system-manager to switch between the available presets:

system-manager switch --sudo --flake <preset>
# Optionally, use my shortcut:
system-switch <preset>

Systems:

• adaliszk#root: empty configuration that only configures Nix itself
• adaliszk#minimal: minimum services and packages for protection and utilities
• adaliszk#k3s: kubernetes node using Rancher's K3s with network-based configuration
• adaliszk#hyprland: core system-level engine for using Hyprland desktop environment

Customization

After the system is initialized, you have the choice to customize-it within your user profile with additional tools and configurations:

nix profile add <profile>

Profiles:

• adaliszk#essentials: core tools and services that are used everywhere (default)
• adaliszk#hyprland: customized Hyprland using Nix and Stow
• adaliszk#terminal: terminal-based "desktop" environment using Nix and Stow
• adaliszk#browser: web browser with its plugins and themes pre-installed
• adaliszk#messaging: various messaging apps for keeping connections up
• adaliszk#kubeadmin: tools for managing kubernetes clusters
• adaliszk#webdev: web-based development editors, plugins, and tools
• adaliszk#phpdev: php-based development editors, plugins, and tools
• adaliszk#minecraft: modded Minecraft gaming and mod development tools
• adaliszk#creator: content creation tools for YouTube and other socials
• adaliszk#agentdev: wrap LLM-based development with fine-tune controls
• adaliszk#neovim: customized neovim using Nix and Stow

After installed the intended profiles, run the config update for setting up the user home configurations:

update-configs

This is also the command to be used for updating the system configs for updates.
