A user's guide (manual) is really needed; the wiki page isn't enough

For the "move rootfs to nvme", I would like to add in advance that you can (almost) fully utilize the nvme SSD (minus the ESP partition - /boot/efi). From the guide I followed, I was able to tinker a bit to make it fully bootable/rebootable. I still need to run a new kernel installation for this to complete my testing but I'm waiting for the next 4.4 ayufan release.
