Minimal OpenSolaris200811 install

Using instructions from Edward Pilatowicz' blog I got small working OpenSolaris 2008.11 in the console version: without Xorg (and Gnome of course).
First of all the list of the core packages for normal work in the console is necessary. My computer has Realtek ethernet adapter and I also have added a SUNWrtls package. Here's example list (pkg.txt):

SUNWcsd
SUNWcs
SUNWzone
SUNWcsl
SUNWlibsasl
SUNWlibms
SUNWpr
SUNWlxml
SUNWzlib
SUNWtls
SUNWopenssl
SUNWpool
SUNWzfs
SUNWsmapi
SUNWtecla
SUNWckr
SUNWpicl
SUNWmd
SUNWinstall-libs
SUNWwbsup
SUNWgccruntime
SUNWcar
SUNWcakr
SUNWusbs
SUNWusb
SUNWaudd
SUNWkvm
SUNWos86r
SUNWrmodr
SUNWpsdcr
SUNWpsdir
SUNWcnetr
SUNWesu
SUNWkey
SUNWnfsckr
SUNWnfsc
SUNWgss
SUNWgssc
SUNWbip
SUNWbash
SUNWloc
SUNWsshcu
SUNWsshd
SUNWssh
SUNWtoo
SUNWzfskr
SUNWipf
SUNWrtls
SUNWipkg
SUNWpython-pyopenssl
SUNWpython-cherrypy
SUNWadmr
SUNWadmap
SUNWadmlib-sysid
SUNWPython
SUNWbzip
SUNWxwrtl
SUNWTk
SUNWTcl
SUNWlexpt
SUNWperl584core

As last versions of packages have dependences, for example SUNWcs is installing SUNWgccruntime, SUNWPython is installing packages SUNWTk and SUNWTcl. But finally I got installed system with size about 280 mb - it's a smaller than 3 Gb;)
I use the same commands as in Edward's blog (I'm running Solaris Express):

zpool create -f rpool c1t1d0s0
zfs set compression=on rpool
zfs create -p rpool/ROOT/indy/opt
zfs set canmount=noauto rpool/ROOT/indy
zfs set canmount=noauto rpool/ROOT/indy/opt
zfs set mountpoint=legacy rpool/ROOT/indy
zfs set mountpoint=legacy rpool/ROOT/indy/opt

# we're going to do our install in /a
PKG_IMAGE=/a; export PKG_IMAGE

# mount our zpool on /a
mkdir -p $PKG_IMAGE
mount -F zfs rpool/ROOT/indy $PKG_IMAGE
mkdir -p $PKG_IMAGE/opt
mount -F zfs rpool/ROOT/indy/opt $PKG_IMAGE/opt

For Solaris Express you must install pkg (not required if you're booting from OpenSolars or MilaX LiveCD):

hg clone ssh://anon@hg.opensolaris.org/hg/pkg/gate
cd gate/src
make install

# create the basic opensolaris install image..
pkg image-create -F -a opensolaris.org=http://pkg.opensolaris.org $PKG_IMAGE
pkg refresh


Note: I use here list of basic packages - pkg.txt (see above):

• 
  

for pkg in `cat pkg.txt`; do pkg install $pkg; done

Next:

• 
  

# seed the initial smf repository
cp $PKG_IMAGE/lib/svc/seed/global.db $PKG_IMAGE/etc/svc/repository.db
chmod 0600 $PKG_IMAGE/etc/svc/repository.db

umount $PKG_IMAGE/opt
umount $PKG_IMAGE
reboot
After reboot you get the console version of OpenSolaris with which you can do all that you want. Next you can install only those packages which are necessary for you. For example it's useful to owners of old notebooks. This installation can be made from an OpenSolaris LiveCD in text mode or with help of a MilaX LiveCD (where's ipkg is included).
