A wrapper script that takes ZFS snapshots prior to nixos-rebuild creating a new system
This wrapper script creates a shell script named `nixos-rebuild-hooked` that reads your `sanoid` config for which datasets are being managed, snapshots them prior to `nixos-rebuild` running. If you are suing `flakes` like I am you can execute rebuild with these features: `nixos-rebuild-hooked switch --flake .`
```nix
{ config, pkgs, ... }:
{
environment.systemPackages = with pkgs; [
(pkgs.writeShellScriptBin "nixos-rebuild-hooked" ''
echo "Running pre-rebuild hook..."

Pinning software with Nix home-manager

Pinning home-manager Packages

Are you using home-manager to install and configure software? Do you have a need to pin specific software versions?

First step is to select the build version of the software. You can go directly to GitHub or any site that distributes the archive of the build. I typically use https://lazamar.co.uk/nix-versions/?channel=nixos-25.05 to search for package URLs. Once you identify the build version you require, use nix-prefetch-url --type sha256 to retrieve and hash the software package.
