nix-config

This repository contains a Nix flake that provides comprehensive configurations for all Linux and macOS machines I manage, alongside development shell environments. This flake ensures consistent system setups and development experiences across all machines running Nix.

Features

1. System Configuration: Centralized configuration management for all my machines. As long as Nix is installed, flakes handle system setup and maintenance, simplifying consistency across environments.
2. Development Shell Environments: Pre-configured development shells for various programming languages and tools, ensuring all necessary dependencies are readily available and correctly set up.

Installation Instructions

Installing Nix

NixOS

To install NixOS, refer to the official NixOS download page for detailed instructions.

macOS

Install Xcode and Homebrew

xcode-select --install
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install Nix on macOS using the following command:

sh <(curl -L https://nixos.org/nix/install)

Linux

Multi-user Installation (Recommended)

For Linux systems with systemd and SELinux disabled, and where sudo authentication is available:

sh <(curl -L https://nixos.org/nix/install) --daemon

Single-user Installation

If the multi-user installation is not feasible:

sh <(curl -L https://nixos.org/nix/install) --no-daemon

This installs Nix as a single-user setup, owned by the invoking user. Run it under your usual account, not as root. The script will use sudo to create /nix if it doesn’t already exist.

Enabling Nix Flakes

To enable Nix flakes, add the following configuration to your nix.conf file:

mkdir -p ~/.config/nix
echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf
