You will now create one MBR partition to contain your OpenBSD data
and one MBR partition on which kernels are located which are loaded
by U-Boot. Neither partition will overlap any other partition.

The OpenBSD MBR partition will have an id of 'A6' and the boot MBR
partition will have an id of '${bootparttype}' (${bootfstype}). The boot partition will be
at least 16MB and be the first 'MSDOS' partition on the disk.

You will now create an OpenBSD disklabel inside the OpenBSD MBR
partition. The disklabel defines how OpenBSD splits up the MBR partition
into OpenBSD partitions in which filesystems and swap space are created.
You must provide each filesystem's mountpoint in this program.

The offsets used in the disklabel are ABSOLUTE, i.e. relative to the
start of the disk, NOT the start of the OpenBSD MBR partition.
