.dotfile — personal Nix developer profile

Declarative environment for:

Host	How it is managed
MacBook M4 (aarch64-darwin)	nix-darwin + home-manager + nix-homebrew
Linux	home-manager only (Ubuntu / WSL2 / Omarchy)

Apply is impure so USER / HOME resolve.

Layout

flake.nix                 # darwinConfigurations.mac + homeConfigurations.me-*
bootstrap-mac.sh          # first-time Mac apply
bootstrap-linux.sh        # first-time Linux apply
rebuild.sh                # daily: re-apply after edits
packages/                 # pinned CLI tools (moon, bun, herdr, …)
modules/
  darwin/                 # Determinate Nix + Homebrew (cleanup = none)
  home/                   # common / linux / omarchy
hosts/mac/                # Mac host glue
files/                    # seed copies into $HOME when missing
scripts/source-overlays.sh

Flake attrs

Host	Flake attr
macOS	.#mac
Ubuntu / WSL2 x86_64	.#me-linux
Ubuntu / WSL2 aarch64	.#me-linux-aarch64
Omarchy x86_64	.#me-omarchy
Omarchy aarch64	.#me-omarchy-aarch64

--impure is required so the flake can read SUDO_USER / USER for your home path.

Env overlays

Login shells source (later wins):

1. $HOME/local.env
2. $HOME/.config/local.env
3. $HOME/.config/me/local.env (non-empty keys only)

ME_INSTALL_PATH defaults to ~/Desktop/Me. ME_KEEP_BASH=1 keeps Bash on Linux instead of exec'ing Zsh.

Secrets stay out of the Nix store.

Fresh Mac

cd ~/.dotfiles
./bootstrap-mac.sh

Later:

sudo env HOME=/var/root USER="$USER" SUDO_USER="$USER" PATH="$PATH" \
  darwin-rebuild switch --impure --flake ~/.dotfiles#mac

Fresh Linux

cd ~/.dotfiles
./bootstrap-linux.sh

Later:

home-manager switch -b before-hm --impure --flake ~/.dotfiles#me-linux

Daily use

cd ~/.dotfiles
./rebuild.sh        # mac on Darwin, me-linux on Linux
./rebuild.sh mac
./rebuild.sh linux

Homebrew note (Mac)

modules/darwin/homebrew.nix sets onActivation.cleanup = "none". Ghostty is a cask. Undeclared brew packages stay installed.

Shell

• zsh via home-manager (autosuggestions + syntax highlighting + oh-my-zsh git)
• starship + zoxide
• auto fast-forward of a clean local main that tracks origin/main
