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.

Here is a simple example for Seafile hosted with Docker in a Compose stack.

For your database network I create it as an --internal network: docker network create --internal your-name-here

Note: Update your email address, volume locations, and password fields

services:
  seafile-db:
    image: mariadb:10.11

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..."

#!/bin/bash

# Set the source and destination directories
SRC_DIR=/path/to/source
DST_DIR=/path/to/destination

# Create the destination directory if it doesn't exist
mkdir -p "$DST_DIR"

# Watch the source directory for new .docx files

Hostname based nix code

You will use hostname = config.networking.hostName; to gather the hostname of the device you are running the nixos-rebuild switch command on

{ config, pkgs, ... }:

let
  hostname = config.networking.hostName;

Are you using Nix? Have you been using oci-containers turing your Docker compose files into systemd podman services?

Probably should check it out, it's sweet!

Note: You must create your mapped volumes locally before the container will start.

Since they have dropped .php the new dashboard URL is http's'://server-ip/admin/login

Lenovo embedded a PreAuthroized OS License for Windows Home edition inside the BIOS. Windows11 tries really hard to force Home edition within a fresh install. How do you bypass this?

Create Windows11 USB, mount and place the following two files under the sources folder inside the root of the live USB.

Note: If creating ei.cfg within notepad, Save-as and "Filetype" set to All Files so the text file saves as a proper .cfg

Otherwise notepad will set the header to plaintext and the installer won't recognize it.
