In my experience, you can just build a zpool and use it to both boot
from and to hold all your data. Creating small boot RAIDs is
unnecessary. The only exception to this is when you want a zpool that
consists of so many disks the BIOS cannot see them all, in which case
you need a smaller pool or somesuch to boot from.
It is generally a bad idea to mix serious usage of ZFS and UFS in the
same server: the different filesystems will tend to fight with each
other over access to memory for caching, and performance will suffer.
