Nix configuration

This repository manages NixOS and Home Manager through a single flake.

Current naming:

• user: javier
• host: poremski
• fqdn: poremski.home.arpa

Main host target:

sudo nixos-rebuild switch --flake ~/.dotfiles#poremski

Current structure:

• lib/hosts.nix: host metadata used to generate flake outputs
• profiles/base.nix: common profile for most machines
• profiles/desktop.nix: desktop-oriented profile layered on top of base
• home/javier/common.nix: shared Home Manager config for the user
• home/javier/poremski.nix: host-specific Home Manager config
• modules/apps: desktop applications shared across hosts, such as Firefox
• modules/cli: CLI tools and terminal programs shared across hosts
• modules/security: shared security-related tooling such as GPG agent integration
• modules/shell: shell configuration shared across hosts
• modules/editors: editor configuration shared across hosts
• modules/nixos/base.nix: shared NixOS base that wires user, profiles and Home Manager together
• modules/nixos/system.nix: NixOS-wide defaults such as Nix settings and core packages
• modules/nixos/locale.nix: timezone, locale and console keymap
• modules/nixos/networking.nix: baseline networking and SSH settings
• modules/nixos/audio.nix: PipeWire and related audio services
• modules/nixos/laptop.nix: laptop-oriented services such as power, fwupd, bluetooth and thunderbolt
• modules/nixos/printing.nix: CUPS, mDNS discovery and printer drivers
• modules/nixos/desktop/plasma.nix: Plasma desktop, SDDM and keyboard layout
• hosts/poremski/default.nix: NixOS host config for poremski
• hosts/poremski/hardware-configuration.nix: host-specific boot, disk and filesystem layout

Available flake targets:

sudo nixos-rebuild switch --flake ~/.dotfiles#poremski
home-manager switch --flake ~/.dotfiles#javier-poremski

To add another host later:

1. Add a new entry in lib/hosts.nix
2. Create home/<user>/<host>.nix
3. Create hosts/<host>/default.nix for that machine's NixOS configuration

Profiles let multiple hosts share the same role without duplicating imports. The shared NixOS base does the same for system-level Home Manager wiring.
