Years and Years ago, when the BeagleBone Black first launched, it
shipped with a bootloader in the eMMC, this looked inside the "first"
partition of the microSD.
We've tried to keep that compatibility where it made sense. And break
it where it made no sense, U-Boot Overlays, BTRFS, etc..

That's really up to you... eewiki is setup to 'teach' you how things
are put together, not make a final image for you. We have other
images that do that..
