❄️ My NixOS Configuration

This directory contains the declarative configuration for my user environment, managed by Home Manager.

🛠️ How it Works (The Nix Way)

In NixOS, configuration files are managed "declaratively" rather than manually.

1. The Source of Truth: Everything is defined in your .nix files.
2. The Nix Store: When you "switch," Nix builds your files and stores them in /nix/store/. These are immutable (read-only).
3. Symlinking: Home Manager creates symbolic links in your home directory (like ~/.pi/agents/settings.json) that point back to that read-only store.

✍️ How to Make Changes

Do not edit the files in your home directory. They are read-only symlinks. To change settings:

1. Edit your source code: Open home.nix in nvim.
2. Modify the Nix block: Locate the home.file section for your agents.
3. Apply changes:

   home-manager switch
   

❓ Why "sudo" doesn't work

The /nix/store is mounted as read-only at the system level. This ensures your system always matches your config and allows for instant rollbacks if something breaks.
