Upgrade a GCP instance group to dual-stack, without restarting/recreating the instances
# Steps to switch a GCE pool from single-stack IPv4 to dual-stack.
#
# These steps avoid recreating VMs in a pool; it happens in-place.
# Step 1: Switch all existing VMs in the pool
# (run once per instance in the group)

Arch Linux Full-Disk Encryption Installation Guide [Encrypted Boot, UEFI, NVMe, Evil Maid]

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.
