Well then, what is this thing you are printing to right now? Silly computer.

Configuring your initramfs can be an adventure. You must either compile-in or include drivers for whatever physical storage you intend to boot from. (had to look up btrfs ... hmmm ...) Yeah, what Humps said, just use ext4.

Love the helpful advice, "See sulogin(8) man page..." from a system in which you cannot "see" anything.
