Bryan Ramos 14efa80cab refactor: reorganize flake structure and consolidate user config 
Directory structure:
- Move from src/ to root level (system/, user/)
- Remove unused machines (workstation, vm, laptop)

User configuration:
- Add user/home.nix for shared defaults (pass, essentials, default modules)
- Centralize user options in user/default.nix
- Move submodules to consistent paths (bash/bash, git/git, neovim/nvim, vim/vim)

Module reorganization:
- Flatten nested module structures (remove /modules/ subdirs)
- Split CLI vs GUI tools (dev/ for CLI, gui/dev/ for GUI)
- Move neovim/vim to top-level modules (not under utils/)
- Remove security.enable - pass now in user/home.nix
- Remove utils.enable - essentials now in user/home.nix
- Add security/yubikey module with yubikey-manager, age-plugin-yubikey
- Move pcb, design to gui/dev/
- Replace penpot docker wrapper with nixpkgs penpot-desktop
- Remove i3 config
- Remove deprecated wsl.nativeSystemd option

GUI improvements:
- Browser-focused mimeApps in gui/default.nix
- Each WM handles its own auto-start via profileExtra

Cleanup:
- Update README with new structure
- Update justfile paths and valid systems
- Fix submodule paths in .gitmodules

NixOS Configuration

Modular NixOS flake configuration with home-manager integration.

Requirements

Flake Outputs

Configuration Description
desktop Primary workstation
server Home server
wsl Windows Subsystem for Linux

Fresh Install

From the NixOS live installer:

# Enable flakes
echo "experimental-features = nix-command flakes" | sudo tee -a /etc/nix/nix.conf

# Clone repo
nix run nixpkgs#git -- clone --recurse-submodules https://github.com/itme-brain/nixos.git
cd nixos

# Enter dev shell and install
nix develop
just install desktop

Getting Started

git clone --recurse-submodules git@github.com:itme-brain/nixos.git
cd nixos
nix develop
just

Note: Replace hardware.nix in system/machines/<machine> with output from nixos-generate-config for your hardware.

Architecture

flake.nix defines NixOS configurations that reference machines under system/machines/.
Each machine imports its hardware, system settings, and home-manager config.

user/home.nix provides shared defaults for all users:

  • Essential packages
  • Default modules

Machine home.nix imports user defaults and enables machine-specific modules.
