Diff to bsdinstall/zfsboot and bsdinstall.8
When I normally install systems I do not like to give the full disk to the zroot partition. If only because I want to use the remainder of the disk for pools of a different ZMIRRO/ZRAID type.
ATM this is only doable by first creating an absurde SWAP size. And once booted fix that. Disadvantage is that the freespace ends between swap and zroot, which is not all to nice.
This patch add a extra option in the zfsboot menu that allows to deviate from the MAX setting. MAX setting gives the current standard behaviour.
