Exactly. What are the differences?

From an organizational structure, I see that buildyourownlinux.com is brought to us by Linux Academy, while linuxfromscratch.org is not affiliated with any other organization (as far as I can tell).

From a technical standpoint, I'm curious what differs. From what I recall, there are several reboots required during LFS - but at first glance I don't see any mention in BYOL.
