Public bug reported:
Conventionally, ZFS is contained within GPT partitions. While setting
up zfs using ubiquity, legacy/bios booted system use MBR partition
tables. This is especially problematic since MBR partitions are
restricted to 2TB.
GPT disks must contain a "Bios_Grub" partition in order to be bootable
from Bios/Legacy systems. This partition can be created using the
command "sgdisk -a1 -n1:256K:+768K -t1:EF02 <disk>", where all the 1's
in that command specify an available partition number.
