Reproducible bootstrap for GitHub Codespace pool machines, driven by Nix + home-manager. No more manual apt install — declare a tool in home.nix, re-run, and every machine converges.

• Installs a modern, flakes-enabled single-user Nix (daemonless — the right fit for systemd-less Codespaces) if it isn't already present.
• Applies the home-manager config in home.nix (tmux, gh, git, ripgrep, fzf, jq, … plus a declarative tmux config with mouse support).

Set this repo as your dotfiles in GitHub → Settings → Codespaces → "Automatically install dotfiles". GitHub clones it and runs install.sh on every new machine.

git clone https://github.com/rfeltis/dotfiles-ms ~/dotfiles-ms
~/dotfiles-ms/install.sh

install.sh is idempotent — safe to re-run.

Edit home.nix, add the package to home.packages, then:

nix run home-manager -- switch --flake ~/dotfiles-ms#"$(whoami)" -b backup

(or just re-run install.sh). Search package names at https://search.nixos.org/packages.

• flake.nix — inputs (nixpkgs 24.11, home-manager 24.11) + a per-user config (node, codespace, vscode, root) so it applies on any base image.
• home.nix — the declarative package set and program config.
• install.sh — Nix install (if needed) + flake apply.
