RestartDK dotfiles

Nix-native dotfiles and host configuration for Daniel's machines.

The canonical editable checkout is:

~/.config/dotfiles

Remote:

https://github.com/RestartDK/dotfiles

Hosts

hosts/srv-nana/                      # NixOS workstation
hosts/twin/                          # reusable Home Manager dev profile
hosts/dkumlin-macbook-pro/           # personal nix-darwin MacBook config
hosts/dkumlin-twin-macbook-pro/      # work nix-darwin MacBook config

Apply configs

Use the traitor wrapper from the repo:

cd ~/.config/dotfiles
./bin/traitor re

Convenience commands:

traitor re          # rebuild current host
traitor check       # run flake checks
traitor update      # update flake inputs
traitor upgrade     # update, then rebuild
traitor rollback    # roll back current host generation
traitor twin        # apply the Home Manager-only twin profile
traitor nana        # rebuild srv-nana explicitly
traitor mac         # rebuild dkumlin-macbook-pro explicitly
traitor work-mac    # rebuild dkumlin-twin-macbook-pro explicitly

Raw commands still work when needed:

sudo nixos-rebuild switch --flake ~/.config/dotfiles#srv-nana
darwin-rebuild switch --flake ~/.config/dotfiles#dkumlin-macbook-pro
darwin-rebuild switch --flake ~/.config/dotfiles#dkumlin-twin-macbook-pro
nix run github:nix-community/home-manager/release-26.05 -- switch --flake ~/.config/dotfiles#twin -b hm-backup

This repo is flake-only; there is intentionally no legacy configuration.nix entrypoint.

Dotfile model

The repo itself is the dotfiles checkout. App config source lives under config/:

~/.config/dotfiles/config/ghostty
~/.config/dotfiles/config/nvim
~/.config/dotfiles/config/pi

Home Manager links selected files into their runtime locations, for example:

~/.config/ghostty
~/.config/nvim
~/.pi/agent/settings.json

High-churn dev and agent config is still managed with explicit out-of-store symlinks:

config.lib.file.mkOutOfStoreSymlink "/absolute/path/to/repo/file"

That keeps those files editable in the Git checkout and avoids copying them into /nix/store. Editing a file under config/ can take effect immediately for live-symlinked apps; rebuilding is needed when changing Nix modules, package lists, services, users, or the set of symlinked paths.

Cobb bridge profile

This flake exports a reusable Home Manager module for Cobb:

inputs.daniel-dotfiles.homeManagerModules.cobb-daniel

The module lives at:

profiles/home/cobb-daniel.nix

It is intended for Cobb's nix/hosts/profiles/daniel.nix to import, while Cobb remains responsible for system users, services, networking, and host-level config. Cobb's NixOS Home Manager module remains the sole activator. The bridge contributes Daniel's development packages and network-namespace wrappers, and points high-churn config at:

/home/daniel/.config/dotfiles

The package and live-config layers only enable on Cobb dev hosts (monster, titan, titan-2).

Rules

• Commit Nix modules and portable dotfiles.
• Do not commit secrets, auth files, tokens, SSH private keys, browser profiles, app databases, sessions, logs, caches, sockets, or generated state.
• Use Home Manager for packages and explicit out-of-store symlink declarations.
• Use NixOS / nix-darwin modules for host/system services.
• Add new Nix files with git add before rebuilding; flakes only see tracked files.
