Void Linux w/ ZFS on Root

This is a personal cheat sheet for myself that I use to install Void Linux. Assumes you're running a x64 CPU, using a NVMe disk at /dev/nvme0n1 and UEFI. If you're attempting this, use hrmpf to install Void Linux, not the live image they provide since it lacks ZFS support. Don't blindly copy/paste shit, you will have to adjust certain commands.

After all this, I generally clone my fork of void-packages with some xbps packages for MEGAsync, import my GPG key, install vscode and whatever else I need.
