You have to modify the x86 miniroot from the original opensolaris dvd.
mv x86.miniroot x86.miniroot.gz
gunzip x86.miniroot.gz
lofiadm -a /<path>/x86.miniroot
mount /dev/lofi/<nr> /mnt/mrmnt
Modifying the miniroot for Jumpstart normally does not require staging it, as
you need to make only two
modifications:
1. Remove the existing symbolic link from the miniroot, and then place the
sysidcfg file in /etc.
# rm /tmp/mrmnt/etc/sysidcfg
# cp sysidcfg /tmp/mrmnt/etc
2. Modify the boot script (/tmp/mrmnt/usr/sbin/install.d/profind) so that it
will pick up a
customized Jumpstart configuration. This involves removing the conditional for
the existence of
/tmp/.preinstall:
cdrom()
{
# Factory JumpStart is only allowed with factory
# stub images, indicated by the file /tmp/.preinstall
#
if [ -f /tmp/.preinstall ]; then <-----------------------------------
Remove this line
mount -o ro -F lofs ${CD_CONFIG_DIR} ${SI_CONFIG_DIR} >/dev/null
2>&1
T
if [ $? -eq 0 ]; then
verify_config "CDROM"
fi
fi <-----------------------------------------------------------------
Remove this line
}
If you goal is to install on different server hardware such as dell 1950 or
2950 or hp, you will have to add extra drivers to the miniroot. This will
involve some extra steps since there is not much free space on the miniroot.
The procedure is well documented in the following guide:

You also have to copy the jumpstart configs to /mnt/dvd/.install_config:
rules , rules.ok begin , finish script + profile
for a complete hands off install you will need to setup a derived profile,
because you cannot gues if the disk will be c0d0 or c0t0d0 or maybe c0d1, so to
solve this you can use a begin script. You need to add probe disks to the rules
file
The JumpStart program sets the SI_DISKLIST, SI_DISKSIZES, SI_NUMDISKS, and
SI_TOTALDISK environment variables which you can use in the begin script
