Braxton's NixOS setup and dotfiles

This repository serves as the documentation for my NixOS setup, dotfiles, and homelab configuration.

Note

This nix configuration is really only designed to work on my personal machines, so there is no guarantee that it will work for you. Feel free to use it as a starting point for your own configuration! Though, if you are running NixOS, I assume you know what you're doing :)

Installing on a clean machine

Using tungsten as an example, follow these steps:

1. Boot into a NixOS live (graphical or minimal) environment (e.g., a USB drive). It seems easier to log in as root.

  sudo su

2. Connect to the internet if necessary.

   sudo systemctl start wpa_supplicant.service
   wpa_cli
   # > add_network
   # > set_network 0 ssid "mynetwork"
   # > set_network 0 psk "mypassword"
   # > enable_network 0
   

3. Clone this repository into your home directory:

    git clone https://code.taxborn.com/taxborn/nixcfg && cd nixcfg
   

4. Format the disk using disko:

    sudo nix --extra-experimental-features "nix-command flakes" run github:nix-community/disko -- --mode disko hosts/tungsten/disks.nix
   

5. Install NixOS:

    sudo nixos-install --flake .#tungsten --root /mnt
   

Building for another machine

Ensure that the target machine and the flake name match... nixos-rebuild switch --flake .#helium-01 --target-host taxborn@100.64.1.0 --sudo --ask-sudo-password --no-reexec

TODO

• Figure out gpg-agent forwarding? maybe only SSH forwarding? I think I want to be able to code on my headless machines (carbon/helium). For that I currently need to forward my GPG agent since I sign code with my PGP key. If I switch to signing with my SSH key, I can probably just forward my SSH agent instead.
• Add more documentation about everything
• Keychron VIA config on Uranium
• Spend a bit of time to figure good config values
  • SSH
  • Boot
  • Kernel
