Sylkos's Dotfiles

Overview

Nix Flake which contains configs for most of my more recent systems. Uses modules for high configurability between systems, organization, and encapsulation of configs for a specific program. Optimized so that adding hosts and programs is easy, and it should be enough to add a new file, then rebuild and everything will work. No need to specify any extra imports.

// ## Hosts

TMP Installation

• clone dots

git clone https://github.com/sylk0s/dotfiles

• format with disko

sudo nix --experimental-features "nix-command flakes" run github:nix-community/disko/latest -- --mode disko hosts/<host-name>/disko.nix

• verify

lsblk

• Generate the hardware config file

sudo nixos-generate-config --no-filesystem --root /mnt

• Copy hardware config

sudo cp /mnt/etc/nixos/hardware-config.nix dotfiles/hosts/<host-name>

• Copy all dotfiles over to the root fs. I do this so I have it after reboot.

sudo cp -r dotfiles /mnt/etc/nixos/

• Change to the new dotfiles

cd /mnt/etc/nixos/dotfiles

• Install with the flake

sudo nixos-install --flake .#<host-name> --root /mnt

Notes:

• will need to create /persist/home/<user> and chmod for each

/* OLD THINGS

• copy and setup dots. will be easier now with some creature comforts
  • copy uuids, copy hardware-config, write host file
  • disable sops and sops-password #TODO auto
• reboot into new system
• impermanence
  • create /persist/home/sylkos (and other users ofc)
  • move in dots
• rebuild and reboot, ensure everything is where we expect and persists
• copy gpg key onto system and into gnupg
  • gpg --import public.key
  • gpg --import private.key
  • gpg --edit-key {KEY} trust quit (this is to modify the permission level of the key)
  • gpg --list-keys
• update sops with passwd
  • get the ssh fingerprint using nix-shell -p ssh-to-age --run "cat /etc/ssh/ssh_host_ed25519_key.pub | ssh-to-age"
  • add to .sops.yaml
  • run nix-shell -p sops --run "sops updatekeys secrets.yaml"
  • re-enable sops
• rebuild into final system :3

Installation

I typically use the gnome install enviornment, since it's just a bit easier to use than minimal, but either are fine. With the gnome install, I install the minimal environment & partiton accordingly and then clone this repo and run the following command.

# nixos-rebuild switch --install-bootloader --flake .#host-name

Note: the --install-bootloader arg may be omitted in certain cases depending on how you want the system to be setup.

After installation

• regenerate SSH keys
• setup folder structure (projects, tools)

Usage

Adding a Host

This repo is designed to make it super easy to add a host!

• create a new folder under hosts/
• copy the hardware config from /etc/nixos/hardware-config.nix
• make any edits needed
• Drawing inspiration from hosts/pc/default.nix or hosts/laptop/default.nix create a host config file
  • Typically, I like a space in the hosts file to quickly add programs to a host without the need to create a module
  • This file is where you setup the modules and make any additional configs you want
• Rebuild into the new host using nixos-rebuild switch --flake .#host-name

Adding a program

This repo is also designed to make it easy to add a program as a module!

• See table below for where to add programs
• If it's not a module, just add the program to a list
• Otherwise, at the appropriate place under modules/ add a new file named module-name.nix and create a module (look to other modules similar for inspiration)

// Places programs are specified

Major Inspiration

• Hlissner's dotfiles
• Auyler's dotifles
