# - First when [Partitioning] select [Shell] and configure network:
#
# # ifconfig "em0" inet "192.168.8.201" netmask "255.255.255.0"
# # route add default "192.168.8.1"
# # echo "nameserver 202.96.134.133" >> /etc/resolv.conf
# # echo "nameserver 8.8.8.8" >> /etc/resolv.conf
#
# - Second fetch the shell file:
#
# # cd /tmp/
# # fetch https ://raw.githubusercontent.com/bleakwind/freebsd/master/zfs_disk.sh && chmod +x zfs_disk.sh
# # at: https ://github.com/bleakwind/freebsd/blob/master/zfs_disk.sh
#
# - Third allocating disk space:
#
# step 1
# # ./zfs_disk.sh -i zroot
#
# step 2
# # ./zfs_disk.sh -o
# # ./zfs_disk.sh -g da0 0 512k 4g 120g
# or # ./zfs_disk.sh -g da0 0
# # ./zfs_disk.sh -g da1 1 512k 4g 120g
# # ./zfs_disk.sh -g da2 2 512k 4g 120g
# # ./zfs_disk.sh -g da3 3 512k 4g 120g
#
# step 3
# # ./zfs_disk.sh -p zroot "raidz2 da0p3.nop da1p3.nop da2p3.nop da3p3.nop"
# or: # ./zfs_disk.sh -p zroot "mirror da0p3.nop da1p3.nop mirror da2p3.nop da3p3.nop"
#
# step 4
# # ./zfs_disk.sh -z zroot auto
# # ./zfs_disk.sh -z zroot "-o mountpoint=/pub zroot/pub"
# # ./zfs_disk.sh -z zroot "-o mountpoint=/db -o recordsize=8K zroot/db"
# # option: -o copies=2
#
# step 5
# # ./zfs_disk.sh -f zroot "da0p3.nop da1p3.nop da2p3.nop da3p3.nop"
#
# step 6
# # rm zfs_disk.sh zfs_disk.sh.log
# # exit
#
# other
# # ./zfs_disk.sh -o
# or: # ./zfs_disk.sh -o da0
# # ./zfs_disk.sh -h
