Void Linux installation (NVMe, btrfs, LVM, full disk encryption using LUKS, 2FA-ish, SSD TRIM)

Encrypted Void Linux setup w/o encrypted boot

This is a guide for installing Void Linux on an EFI system with non encrypted boot and encrypted root. The guide is based on practical paranoid article and official Void Linux article.

I wrote this guide to help myself installing Void Linux w/o encrypted boot. I haven't checked it for grammar errors, so there might be some. I hope it will help you, and good luck. And I know that I use way to many pictures/terminal copy paste.
