Solved [Solved] Install FreeBSD 9 without bsdinstall

Recently rented remote server and by default it comes with FreeBSD9.1 amd64 on UFS. Only one hard drive available. The problem is that provider offers only FreeBSD recovery CD. So I need to install ZFS using recovery without having the automatic bsdinstall installer.
My steps:
Code: 
gpart destroy -F ada0
gpart create -s gpt ada0
add -b 34 -s 64k -t freebsd-boot ada0
gpart add -s 4G -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 show
=>        34  3907029101  ada0  GPT  (1.8T)
          34         128     1  freebsd-boot  (64k)
         162           6        - free -  (3.0k)
         168     4194304     2  freebsd-swap  (4.0G)
     4194472  3902834656     3  freebsd-zfs  (1.8T)
  3907029128           7        - free -  (3.5k)

From this point don't know how to proceed to base.txz kernel.txz bootstraping.
Server configuration: Intel Core i3, 8 GB RAM, 2 TB HDD
 
I suggest something like the following (attention, I don't check if I missed something, so think over it):

# kldload zfs
# zpool create zroot /dev/gpt/disk0
# zpool set bootfs=zroot zroot
# fetch [url=ftp://ftp.freebsd.org/pub/FreeBSD/releases/amd64/9.2-RELEASE/base.txz]ftp://ftp.freebsd.org/pub/FreeBSD/relea ... E/base.txz[/url]
# tar xfp base.txz -C /zroot
repeat for kernel.txz and eventually for lib32.txz
# chroot /zroot
# echo 'zfs_enable="YES"' > /etc/rc.conf
# echo 'hostname="_hostname here_"' >> /etc/rc.conf
# echo 'ifconfig_XX0="DHCP"' >> /etc/rc.conf
# echo 'zfs_load="YES"' > /boot/loader.conf
# echo 'vfs.root.mountfrom="zfs:zroot"' >> /boot/loader.conf
# passwd
# tzsetup

Don't forget to also create /etc/fstab with a line for the swap inside.
 
Thanks for the manuals!
Since my server in OVH, searched bit specific info and found here http://kdl.nobugware.com/post/2012/02/07/freebsd-90-zfs-root-ovh
Then adapted for one hard drive. Everything seems fine until i do
Code: 
rescue-bsd# zfs set mountpoint=legacy rpool/root
cannot unmount '/tmp/mntzfs': Device busy

To be quick i have created bash script
Code: 
#!/bin/sh

#Create slices
gpart destroy -F ada0
gpart create -s gpt ada0
gpart add -b 34 -s 64k -t freebsd-boot ada0
gpart add -s 4G -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 

#Create ZFS
zpool create -o cachefile=/boot/zfs/zpool.cache -m none -f rpool /dev/gpt/disk0 
zfs set checksum=fletcher4 rpool 
zfs create rpool/root 
mkdir /tmp/mntzfs 
zfs set mountpoint=/tmp/mntzfs rpool/root  
zfs create -o canmount=off  rpool/root/usr 
zfs create  -o canmount=off rpool/root/var 
zfs create -o compression=on -o exec=on -o setuid=off rpool/root/tmp

zfs create -o compression=gzip -o exec=off -o setuid=off  rpool/root/usr/src 
zfs create -o compression=lzjb rpool/root/usr/obj 
zfs create -o compression=lzjb  -o exec=off     -o setuid=off   rpool/root/var/crash 
zfs create -o compression=off -o exec=off -o setuid=off   rpool/root/var/empty 
zfs create -o compression=lzjb  -o exec=on -o setuid=off   rpool/root/var/tmp  
zpool export rpool 
zpool import -o cachefile=/tmp/zpool.cache rpool 
chmod 1777 /tmp/mntzfs/tmp 
chmod 1777 /tmp/mntzfs/var/tmp

That keeps showing up, it must be in some common article. I think it is sub-optimal. This is better, creating an aligned boot partition (which does not really matter) that is the maximum allowed size:
Code: 
gpart add -t freebsd-boot -l gpboot -b 40 -s 512K ada0

Add the first filesystem partition starting at block 2048 (1M) for compatibility with other software and alignment:

Code: 
gpart add -b 2048 -s 4G -t freebsd-swap -l swap0 ada0
 
Great, thank you! Installation accomplished fine and system rebooted to FreeBSD 9.2 on ZFS.

Still missed something:
Code: 
portsnap fetch
Looking up portsnap.FreeBSD.org mirrors... none found.
Fetching public key from portsnap.FreeBSD.org... failed.
No mirrors remaining, giving up

Also a question, it is ok for my configuration to keep 8 GB swap on ZFS? Machine planned as web server to host plenty of dynamic websites.

Current status:
Code: 
 zfs list
