nixcfg

Nix rules everything around me

• Overview
• Components
• Repo Layout
• Secrets
• Other Interesting Nix Repos

Overview

• nix configuration for my laptops, desktops, sbcs, phones, and cloud servers
• nix flake-powered
• guaranteed to be reproducible
• immutable full system configuration (dotfiles, but on steroids)

notes

• some commits may have empty commit messages, this is from me attempting to use and learn jj.

Components

• home-manager for user-based app/desktop configuration
• sops-nix for secrets (encrypted at rest, per-host encryption)
• terranix for cloud server creation/deletion automation
• custom commands for easy gpg-over-ssh usage (pkgs/commands.nix)

Repo Layout

(this sometimes drifts, but should be roughly accurate as of April 2023)

• cloud
  • automation and configuration for cloud servers
  • powered by terranix
• docs
  • notes to self
  • who knows what "great" ideas and tidbits it contains
