I think it's worth the effort to try to understand gpart et al.
If you have a new disk, DISK=3Dad4, for example
# remove any possible existing data at beginning and end of disk (this
is just an example)
offset=3D`diskinfo $DISK | awk '{ print $4 - 131072 }'`
dd if=3D/dev/zero of=3D/dev/$DISK bs=3D64k count=3D1
dd if=3D/dev/zero of=3D/dev/$DISK bs=3D64k seek=3D$offset
The following is for a boot drive, with some fixed ideas about
partitions, but is possibly useful as an example. The assumption here
is alignment to 64k boundaries. If you don't need a bootable drive,
just skip the parts for that. You could create one big partition, if
that's what you want, with just the last bit.
# create partition table
gpart create -s gpt ${DISK}
# add boot partition
# p1
gpart add -t freebsd-boot -l boot -s 64k ${DISK}
# put boot code in boot partition
gpart bootcode -b /boot/pmbr -p /boot/gptboot -i 1 ${DISK}
# add 1G root, make sectors aligned
# p2
gpart add -t freebsd-ufs -l root -a 64k -s 1G ${DISK}
# add 2G swap
# p3
gpart add -t freebsd-swap -l swap -a 64k -s 2G ${DISK}
# add 1G tmp
# p4
gpart add -t freebsd-ufs -l tmp -a 64k -s 1G ${DISK}
# add 2G var
# p5
gpart add -t freebsd-ufs -l var -a 64k -s 2G ${DISK}
# add 2G opt
# p6
gpart add -t freebsd-ufs -l opt -a 64k -s 2G ${DISK}
# add remainder of disk for usr
# p7
gpart add -t freebsd-ufs -l usr -a 64k ${DISK}
