Minimal OpenSolaris SPARC install

Using previous instructions I've successfully installed opensolaris 2009.06 on my TestFarm (thanks, Jim) T2000 from existing Nevada b98.
Steps are identical: my machine have 4 disks, so I've prepared third disk (c0t2d0) for installation (I take 4gb):

Part      Tag    Flag     Cylinders         Size            Blocks
  0       root    wm       0 -   824        4.00GB    (825/0/0)     8395200
  1 unassigned    wm       0                0         (0/0/0)             0
  2     backup    wu       0 - 14086       68.35GB    (14087/0/0) 143349312
  3 unassigned    wm       0                0         (0/0/0)             0
  4 unassigned    wm       0                0         (0/0/0)             0
  5 unassigned    wm       0                0         (0/0/0)             0
  6 unassigned    wm       0                0         (0/0/0)             0
  7 unassigned    wm       0                0         (0/0/0)             0

Next steps (it's fast):

zpool create opensolaris c0t2d0s0
zfs create opensolaris/rootfs
zfs set compression=on opensolaris/rootfs
zfs set mountpoint=legacy opensolaris/rootfs
mkdir /zfsroot
mount -f zfs opensolaris/rootfs /zfsroot

I already have pkg built and installed from sources on my Nevada. Now network installation:

pkg image-create -F -f -a opensolaris.org=http://pkg.opensolaris.org /zfsroot

cd /zfsroot

for pkg in `cat pkg.lst`; do  pkg install --no-refresh --no-index $pkg; done

echo "etc/zfs/zpool.cache" >> /zfsroot/boot/solaris/filelist.ramdisk

zpool set bootfs=opensolaris/rootfs opensolaris

echo "opensolaris/rootfs   -  /   zfs  -  no   -"  >> /zfsroot/etc/vfstab

mkdir -p /opensolaris/platform/sun4v

cp /zfsroot/platform/sun4v/bootlst /opensolaris/platform/sun4v/

cp /zfsroot/lib/svc/seed/global.db /zfsroot/etc/svc/repository.db      

devfsadm -R /zfsroot

bootadm update-archive -R /zfsroot

installboot -F zfs /platform/sun4v/lib/fs/zfs/bootblk /dev/rdsk/c0t2d0s0

This install take only 630 mb. Now I can adjust my network settings and install additional packages.
