Applying Configuration

Test a configuration without switching:

sudo nixos-rebuild test --flake .#miku-homelab

Apply permanently:

sudo nixos-rebuild switch --flake .#miku-homelab

Update flake inputs:

nix flake update

Home Manager

Home Manager is integrated as a NixOS module.

User configuration is located in:

home/emmatherock/

Desktop applications, development tools, gaming utilities, shell configuration, and editor configuration are managed there.

Design Principles

System configuration lives under modules/system.
Desktop-specific configuration lives under modules/desktop.
User applications and preferences belong in Home Manager whenever possible.
Drivers, hardware, networking, audio services, and boot configuration remain managed by NixOS.
Each module should have a single responsibility.
Changes should be incremental and easy to review.

Rebuilding

After modifying the configuration:

sudo nixos-rebuild test --flake .#miku-homelab

If everything works:

sudo nixos-rebuild switch --flake .#miku-homelab
