== Laptop ==
Greeting, I had a bit time, free slice on the disk with MBR and the desire to play with the new installation of FreeBSD 9.0-RC1 .
Below is just a simple example ; there will be one ZFS filesystem on /, no swap, no keys for GELI, passphrase only. Nevertheless, I decided to share the method which can be used in different setups and configurations.


=== Load Geli ===
My setup consists of:
ada0 - hard drive
ada0s1 - slice will be used for boot 1G
ada0s2 - slice will be used for swap 4G
ada0s3 - slice will be used for ZFS  50G


Fixit> kldload geom_eli
1. Boot with your FreeBSD install disk and choose “Live CD” when prompted, login as root, no password is required.
2. This step is optional but it's a good idea.
Code:


=== Festplatte ===
dd if=/dev/urandom of=/dev/ada0s1
dd if=/dev/urandom of=/dev/ada0s3


Fixit> gpart create -s GPT ada0
3. bsdlabeling:
Fixit> gpart add -s 64K -t freebsd-boot ada0
Code:
Fixit> gpart add -s 1G -t freebsd-ufs ada0
Fixit> gpart add -s 55G -t freebsd-zfs ada0
Fixit> gpart set -a active -1 ada0 # funzt nicht
Fixit> gpart bootcode -b /dist/boot/pmbr -p /dist/boot/gptzfsboot -i 1 ada0
Fixit> newfs -O2 /dev/ada0p2


*aktuelle Festplatten Einteilung
bsdlabel -w /dev/ada0s3
-ad0 GPT
    |-1 freebsd-boot 64K
    |-2 freebsd-ufs 1G /boot
    |-3 freebsd-zfs 55G / (crypto)


=== Encrypt ===
4. Loading the required modules:
Code:


Fixit> geli init -b -s 4096 -l 256 /dev/ada0p3
kldload geom_eli zfs


=== Attach ===
5. Labeling partition:
Code:


Fixit> geli attach /dev/ada0p3
glabel label zrpool /dev/ada0s1a


=== ZFS ===
6. Initiation and attachment GELI:
Code:


Fixit> kldload zfs
geli init -b /dev/label/zrpool
Fixit> zpool create tank /dev/ad0p3.eli
geli attach /dev/label/zrpool
# Fixit> zpool create home
# Fixit> zpool set bootfs=tank tank
# Fixit> mkdir /tank/bootdir
# Fixit> mount /dev/ad0p2 /tank/bootdir
Fixit# zfs set checksum=fletcher4                                      zroot
Fixit# zfs create -o compression=on    -o exec=on      -o setuid=off  zroot/tmp
Fixit# chmod 1777 /zroot/tmp
Fixit# zfs create                                                      zroot/usr
Fixit# zfs create                                                      zroot/usr/home
Fixit# cd /zroot ; ln -s /usr/home home
Fixit# zfs create -o compression=lzjb                  -o setuid=off  zroot/usr/ports
Fixit# zfs create -o compression=off  -o exec=off    -o setuid=off  zroot/usr/ports/distfiles
Fixit# zfs create -o compression=off  -o exec=off    -o setuid=off  zroot/usr/ports/packages
Fixit# zfs create -o compression=lzjb  -o exec=off    -o setuid=off  zroot/usr/src
Fixit# zfs create                                                      zroot/var
Fixit# zfs create -o compression=lzjb  -o exec=off    -o setuid=off  zroot/var/crash
Fixit# zfs create                      -o exec=off    -o setuid=off  zroot/var/db
Fixit# zfs create -o compression=lzjb  -o exec=on      -o setuid=off  zroot/var/db/pkg
Fixit# zfs create                      -o exec=off    -o setuid=off  zroot/var/empty
Fixit# zfs create -o compression=lzjb  -o exec=off    -o setuid=off  zroot/var/log
Fixit# zfs create -o compression=gzip  -o exec=off    -o setuid=off  zroot/var/mail
Fixit# zfs create                      -o exec=off    -o setuid=off  zroot/var/run
Fixit# zfs create -o compression=lzjb  -o exec=on      -o setuid=off  zroot/var/tmp
Fixit# chmod 1777 /zroot/var/tmp


=== Install FreeBSD ===
7. Creation ZFS pool and FS:
Code:


Fixit> zfs set mountpoint=/tank/usr/home home
zpool create -O mountpoint=/mnt -O canmount=off zrpool /dev/label/zrpool.eli
Fixit# cd /dist/8.2-*
zfs create -o mountpoint=legacy zrpool/FreeBSD
Fixit# export DESTDIR=/zroot
Fixit# for dir in base catpages dict doc games info lib32 manpages ports; \
          do (cd $dir ; ./install.sh) ; done


*lib32 oder  proflibs
8. Installation FreeBSD:
Code:


Fixit# cd src ; ./install.sh all
mount -t zfs zrpool/FreeBSD /mnt
Fixit# cd ../kernels ; ./install.sh generic
tar -xf /usr/freebsd-dist/base.txz -C /mnt
Fixit# cd /zroot/boot ; cp -Rlp GENERIC/* /zroot/boot/kernel/
tar -xf /usr/freebsd-dist/kernel.txz -C /mnt


Fixit# zfs set readonly=on zroot/var/empty
You can select and install something else, please take a look at /usr/freebsd-dist/
9. ada0s1, preparation:
Code:


=== post install ===
bsdlabel -B -v /dev/ada0s1
newfs /dev/ada0s1a


Fixit# chroot /zroot
10. Copying /boot to ada0s1:
Code:


*rc.conf
mkdir /tmp/boot
zfs_enable="YES"
mount /dev/ada0s1 /tmp/boot
hostname="beastie.mydomain.local"
cp -Rp /mnt/boot /tmp/boot/
ifconfig_re0="DHCP"


*loader.conf
11. Creation fstab and loader.conf:
zfs_load="YES"
a) create /tmp/usbboot/boot/loader.conf and add the following lines:
vfs.root.mountfrom="zfs:zroot"
Code:
geom_eli_load="YES"
geli_ad0p4_keyfile0_load="YES"
geli_ad0p4_keyfile0_type="ad0p4:geli_keyfile0"
geli_ad0p4_keyfile0_name="/boot/key/ad0.key"


*fstab
geom_eli_load="YES"
# Device                      Mountpoint              FStype Options        Dump    Pass#
zfs_load="YES"
/dev/ad0s2                    /bootdir                ufs    rw              0      0
# aesni_load="YES" # option see man aesni
vfs.root.mountfrom="zfs:zrpool/FreeBSD"


b) create /mnt/etc/fstab:
Code:


Fixit> passwd
# cat > /mnt/etc/fstab
Fixit> tzsetup
zrpool/FreeBSD / zfs rw 0 0
Fixit> cd /etc/mail
^D
Fixit> make aliases
Fixit> umount /dev
Fixit> exit
Fixit# cp /boot/zfs/zpool.cache /zroot/boot/zfs/zpool.cache
Fixit> mkdir /tank/boot/key
Fixtit> cp /boot/key/* /tank/boot/key


=== Finish install ===
12. Generation and recording zpool.cache to USB stick:
Code:


Fixit# cd /zroot
zpool export zrpool
Fixit# mv boot bootdir/
zpool import -o cachefile=/tmp/usbboot/boot/zfs/zpool.cache zrpool
Fixit# ln -s bootdir/boot /zroot/boot
Fixit# chflags -h sunlink /zroot/boot


Fixit# export LD_LIBRARY_PATH=/mnt2/lib
13. Change pool mountpoint to /
Code:


Fixit# umount /zroot/bootdir
zfs set mountpoint=/ zrpool
Fixit# zfs unmount -a


Fixit# zfs set mountpoint=legacy zroot
14. Finish.
Fixit# zfs set mountpoint=/tmp zroot/tmp
Code:
Fixit# zfs set mountpoint=/usr zroot/usr
 
Fixit# zfs set mountpoint=/var zroot/var
shutdown -r now
Fixit# zfs set mountpoint=/usr/home home
