Personal NixOS configurations with home-manager as OS module(and as a stand alone for generic GNU/Linux) in a flake. This repository is a work in progress, containing configuration files for my various machines.

Disclaimer

Since I'm employing sops-nix for secret management (such as user password) within this repository, complete deployment is not feasible without the necessary encryption key. Consequently, certain configurations will not function properly.

Use this repository as a blueprint for setting up your own system. The individual configuration files (such as tmux, neovim, etc.) can serve as a reference.

Design philosophy

• Multiple machines are defined with emphasis on shared code between them in order to achieve consistency and to avoid code repeat where possible.
• Work flow is heavily skewed towards the use of the keyboard and the terminal. Some keyboard bindings may look strange but they are effected by the fact that I am using a programmable keyboard(configurations in my Adv360-Pro-ZMK repo).
• Lacking functionality is extended by scripts(such as Firefox bookmarks for rofi).
• Effort has been made to define everything using nix, including the $HOME dotfiles to the possible extent.

Highlights

• Multiple host configurations using home-manager as a NixOS module, allowing for shared configurations across systems, with an option for standalone home-manager configurations to be used on generic Linux hosts, such as Ubuntu.
• Secrets deployment using sops-nix.
• Extensively configured xorg and terminal environment.
• Configuration for KVM, VirtualBox, and docker.
• Integration of disko to partition hard drives during NixOS installing and to create /etc/fstab.

Daily driver software

• Desktop: xorg with i3 and polybar.
• Launcher: Rofi.
• Shell: zsh + starship with fzf and atuin integration.
• Editor: neovim.
• Terminal: alacritty(with tmux).
• Second brain: emacs(org-roam).

Some of the services I use

• ssh-agnet(via gpg-agnet): For all my ssh needs.
• emacs server.
• clipmenu: a clipboard history via rofi.
• redshift: Adjusts the color temperature of your screen according to your surroundings.
• dnust: notification daemon.
• sxhkd: A simple X hotkey daemon.
• syncthing: sync files between all of my hosts.
• tmux: Used to start tmux on boot and with the resurrect and continuum plugins my entire terminal environment is ready for me on boot.
• watchman: Used to watch a directory and on any change in it to trigger actions. I used it to rsync files I changed locally to a remote automatically.
• moolticuted: a daemon used to interact with mooltipass the hardware password manager.

Repo structure

• flake.nix: The entry point for hosts and home configurations.
• hosts: The machines that can be configured using this repository. With each host having its high level .nix configuration that define host specific settings and include code that can be shared with other hosts.
• modules: Divided into modules to be used by home-manger(including user scripts) to mange user configuration and into nixos modules which are mostly configurations I found in /etc/nixos/configuration.nix and refactored into responsibilities that can then be including by the various hosts to achieve code reuse.
• wallpaper: self explanatory :)

ToDo

• [ ] Look into streamlining installation process of NixOS on a new host with nixos-anywhere.
• [ ] Replace default way to mount hard drives with a generic one in the form of disko.
  • [ ] Update all hosts to use disko.
• [ ] I am not sure that emacs systemd unit can communicate with ssh-agnet, this is a very low priority.
• [ ] Stream line the use of nix-index.
• [ ] Look into automating home-manger installation as a stand alone on generic Linux using Ansible.
