nixos

NixOS and Home Manager configurations for my machines.

Flake attribute	Host	Machine
nixUltra	hosts/nixUltra	HP ZBook, the daily laptop
nixWorks	hosts/nixBlade	Framework laptop
omegaServ	hosts/omegaServ	Home server: Matrix, Minecraft, WireGuard
phantomServ	hosts/phantomServ	Home Assistant and media
nixUltraInstaller	hosts/nixUltra/installer.nix	Install ISO for nixUltra

Switching

nixswitch     # sudo nixos-rebuild switch --flake ~/nixos#<this machine>
homeswitch    # home-manager switch --flake ~/nixos#<this machine>
nixtest       # nixos-rebuild test, nothing made permanent

The aliases come from modules/home-manager/term/zsh.nix and pick the machine from custom.flakeAttr.

Layout

• flake.nix: inputs and the host list. Every machine gets the same package set: stable nixpkgs, plus pkgs.unfree, pkgs.unstable.unfree and pkgs.master.unfree.
• hosts/<host>/: configuration.nix, home.nix and hardware for one machine. hosts/laptop/ holds the files both laptops import, home included; nixBlade uses that home as it is.
• modules/nixos/: system modules every host imports; head/ is the desktop, serv/ the services.
• modules/home-manager/: desktop/, term/ (shell, editors, AI tools) and themes/. graphide.nix is the Graphide setup, imported by the laptops.
• confs/: config that is not Nix (Neovim, the browser start page).
• pkgs/, scripts/: one local package and a few one-off machine scripts.

Graphide

graphide-autoupdate keeps the released gr and grug in a Nix profile of its own, so no Graphide release is pinned here. graphide-tools pins GraphideHQ/graphide-tools: the shared Home Manager modules, grail, gdev and the internal scripts, which left the monolith when it was split (2026-10-28). It locks the monolith it builds against itself. graphide-website supplies the brand mark fastfetch draws. Bump them with upstream Nix, since Lix cannot resolve graphide-tools' monolith input by its branch ref:

nix run nixpkgs#nixVersions.latest -- --extra-experimental-features 'nix-command flakes' \
  flake update graphide-tools graphide-website

Codex goes through the shared account pool on XiaServer (modules/nixos/codex-pool.nix), and ai-pool claude runs Claude through it. Local sign-ins stay with the account wrappers in modules/home-manager/term/ai/accounts.nix.
