You will now create a single MBR partition to contain your OpenBSD data. This
partition must have an id of 'A6'; must *NOT* overlap other partitions; and
must be marked as the only active partition.

The 'manual' command describes all the fdisk commands in detail.

$(fdisk ${_disk})
__EOT
	fdisk -e ${_disk}

	cat <<__EOT
Here is the partition information you chose:

$(fdisk ${_disk})
__EOT
}

md_prep_disklabel() {
	local _disk=$1

	md_prep_fdisk $_disk

	cat <<__EOT

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.

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.
