Arch Linux Full-Disk Encryption Installation Guide

This guide provides instructions for an Arch Linux installation featuring full-disk encryption via LVM on LUKS and an encrypted boot partition (GRUB) for UEFI systems.

Following the main installation are further instructions to harden against Evil Maid attacks via UEFI Secure Boot custom key enrollment and self-signed kernel and bootloader.

Preface

You will find most of this information pulled from the Arch Wiki and other resources linked thereof.

Note: The system was installed on an NVMe SSD, substitute /dev/nvme0nX with /dev/sdX or your device as needed.

Upgrade Qbittorrent HTTP Announces to HTTP/2

Motivation

You probably don't want to do what is described in this document. Seriously consider just leaving things alone.

Because Qbittorrent, and most all torrent clients, still use HTTP/1.1, they typically do not reuse connections for multiple announces of different torrents to the same tracker announce URL. As the number of torrents goes up, there ends up being a lot of traffic back and forth just re-establishing a connection for each announce. This is highly inefficient, and while it is not really a problem for most users, or even most tracker operators, it is something that can start to be noticed at at the tracker level at a very large scale.

Using a more modern protocol, like HTTP/2, addresses this inefficiency by reusing an established connection. Unfortunately, Transmission is really the only torrent client that implements HTTP/2 right now. For Qbittorrent, the issue resides in an underlying library, libtorrent. The issue was raised in 2020,
