Voidlinux with encrypted root on Raspberry Pi

So I have decided to go Void Linux on all my machines. One of the advantages for me was the absence of systemd and the presence of musl libc, my admiration for which I shared in a recent blog post about Alpine Linux. I was trying to find a tutorial on how to make an encrypted root partition work with Raspberry Pi. I have a strong belief that all offline storage should be encrypted today.
