Raspberry Pi Encrypted Root Partition + btrfs Headless Setup Guide

This is a step-by-step guide for making your Raspberry Pi 5 more secure and powerful by using encrypted rootfs and btrfs. It is highly recommended to use NVME drive as a boot device for this setup to work properly.

This method of installation is completely headless, but can also be performed on the device itself.

All commands in this guide are executed from root account (aka with sudo).
