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.

Hibernate when battery is critical level using systemd-timers

The following script will check if the battery is in critical state, and launch the lock and hibernate sequence correspondingly.

Put the file in /home/$USER/.bin/hibernate_critical_bat.sh

Here the critical level is set to 8, in if [ "$status" = Discharging -a "$capacity" -lt 8 ]; then
