BUGS
The boot code of FreeBSD assumes that the file system that carries the
kernel has blocks of 8 kilobytes and fragments of 1 kilobyte. You will
not be able to boot from a file system that uses another size.

So I'd assume you have to be careful to leave the root at the current
defaults? (or make the boot code smarter?)
