nixos-config

My "flake"-less Nix configuration for NixOS, macOS, and WSL.

This project documents my journey through learning Nix(OS), and largely using NixOS as my sole development environment, via a VM, running aarch64 NixOS, on a macOS laptop (MacBook Pro).

Ideally, I'm trying to keep flakes¹ out of this project. I will use third-party apps (e.g. disko) which may, themselves, use flakes, where applicable.

Configuration

TBD

Install

Expects to be run on a NixOS Minimal ISO Image.

Use either the Online Install or Local Install instructions.

Installation Process

1. Partitions the disk, then formats and mounts the partitions. Uses a similar process to the one outlined in NixOS Manual Installation.

2. Uses, or retrieves, from GitHub, this Custom Configuration.

3. Generates a basic configuration, which seems to be required for nixos-install.

4. Installs, via nixos-install, from this Custom Configuration.

5. Using the newly created /etc/passwd does the following:

   1. Prompts for user to own /mnt/etc/nixos/config directory.

   2. Asks if users' chezmoi dotfiles should be retrieved from GitHub.

      This is a Work in Progress and currently pretty rudimentary.

      • If yes, then loops though each user, asking to retrieve dotfiles for that user.
        • If yes, then retrieves the dotfiles to /home/<user>/dotfiles from GitHub using the following URL: https://github.com/<user>/dotfiles.git.
        • Asks if chezmoi install should be run at user's first login

          • If yes, then creates a script file and adds it to all login files for the user, i.e. /home/<user>/.{bash_profile,login,profile,zprofile}, to run chezmoi install file from dotfiles directory, i.e.

            sh "${HOME}/init-chezmoi.sh" && exec ${SHELL}

          • The script file init-chezmoi.sh does the following:

            • Run ${HOME}/dotfiles/install.sh.
            • Removes the calls to init-chezmoi.sh from the login files, i.e. /home/<user>/.{bash_profile,login,profile,zprofile}.
            • Removes itself, i.e. ${HOME}/init-chezmoi.sh.

6. Asks if the system should reboot.

Online Install

1. On the live Minimal ISO Image, run the following command:

   sh <(curl -fsSL https://raw.githubusercontent.com/jwinn/nixos-config/main/install.sh)

Local Install

1. On the live Minimal ISO Image, run the following to get the IP address:

   ip route get 1.1.1.1 | grep -oP 'src \K[^ ]+'

2. On the live Minimal ISO Image, update the default nixos user to have a password.

   passwd

3. Copy the Custom Configuration to the above IP, usually done through scp, e.g.

   scp -r nixos-config nixos@<ip_address>:~/

4. On the live Minimal ISO Image, run the install script.

   cd nixos-config && sh install.sh cd -
