**Pull when git is not in PATH** (e.g. before first rebuild or when `sudo git` says "command not found"):
```bash
sudo nix run nixpkgs#git -- -C /etc/dotfiles pull origin main
```
Then run `sudo nixos-rebuild switch --flake /etc/dotfiles/nixos#nixos-server` as usual. After that, git is in the system profile; for manual pulls you can use `sudo /run/current-system/sw/bin/git -C /etc/dotfiles pull origin main` if `sudo git` still isn’t in PATH.
