The biosboot (ie. boot sector) must be able to load the /boot file. Then, the /boot file must be able to load the kernel. Both need to be BIOS-reachable. You don't want a giant root file system. It won't work. We actually have other reasons to have our users not use giant root filesystems. It is not as secure.
