Installing FreeBSD 9.0-RELEASE Root on ZFS using GPT

This memo is my log during installing 9.0-RELEASE with new bsdinstaller.

WARNING! please update if errors found, or merge this text to other pages.

  1. Boot FreeBSD install DVD or USB Memstick
  2. Choose Shell option at Partitioning dialog in bsdinstall
  3. Create partitions 
     # gpart create -s gpt ada0
 # gpart create -s gpt ada1

 # gpart add -s 64K -t freebsd-boot -l boot0 ada0
 # gpart add -s 8G -t freebsd-swap -l swap0 ada0
 # gpart add -t freebsd-zfs -l disk0 ada0
 # gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0

 # gpart add -s 64K -t freebsd-boot -l boot1 ada1
 # gpart add -s 8G -t freebsd-swap -l swap1 ada1
 # gpart add -t freebsd-zfs -l disk1 ada1
 # gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1

 # zpool create -o altroot=/mnt zroot mirror /dev/gpt/disk0 /dev/gpt/disk1
 # zfs create zroot/tmp
 # chmod 1777 /mnt/tmp
 # zfs create zroot/usr
 # zfs create zroot/var
 # zfs create zroot/home
 # exit
  4. After exiting from shell, proceed installation

  5. When asked to create partitions, select "Shell", then type exit.

  6. When installation is finished, choose Live CD option and login as root
  7. Fix mountpoint and zpool cachefile 
     # echo 'zfs_enable="YES"' >> /mnt/etc/rc.conf
 # echo 'zfs_load="YES"' >> /mnt/boot/loader.conf
 # echo 'vfs.root.mountfrom="zfs:zroot"' >> /mnt/boot/loader.conf
 # zfs unmount -a
 # zpool export zroot
 # zpool import -o cachefile=/tmp/zpool.cache -o altroot=/mnt zroot

 # zfs set mountpoint=/ zroot
 # cp /tmp/zpool.cache /mnt/boot/zfs/
 # zfs unmount -a
 # zpool set bootfs=zroot zroot
 # zpool set cachefile='' zroot
 # zfs set mountpoint=legacy zroot
 # zfs set mountpoint=/tmp zroot/tmp
 # zfs set mountpoint=/usr zroot/usr
 # zfs set mountpoint=/var zroot/var
 # zfs set mountpoint=/home zroot/home
  8. after these commands, type reboot from Live CD to finish installation
