I've used a script like the one appended below to build a customized
(Open-)Solaris
installation optical media. The attached script replaces stage2
stage2_eltorito and
multiboot on the installation CD; these three files are not included, but you
should get an
idea how to build a customized version of the Installation media.

then
echo "$USAGE"
exit 2

for i in $*
do
case $i in
-d) tmp_dir=$2; shift 2;;

if [ $# -ne 2 ]

exit 2

dev_lofi=/dev/lofi/99
mnt=/tmp/mnt_iso_$$

#
# map the solaris installation cd/dvd image to a lofi device,

lofiadm -a "$img" $dev_lofi
[ $? -ne 0 ] && exit 1
mkdir -p $mnt
mount -F hsfs $dev_lofi $mnt
[ $? -ne 0 ] && exit 1

# copy the cd/dvd image to a temporary directory so that we
# can modify it

echo "building iso in $tmp ..."
mkdir -p "$tmp"
(cd $mnt; tar cf - .) | (cd "$tmp"; tar xf -)
umount $mnt
rmdir $mnt
lofiadm -d $dev_lofi
#
# replace the stage2 grub boot code
# (fixes 6412224 GRUB hangs when no i8042 is present)
# replace multiboot
# (fixes 6412226 multiboot hangs when no i8042 is present)
#
cp -f stage2 stage2_eltorito "$tmp/boot/grub/"
cp -f multiboot "$tmp/boot/"
#
# and build a new iso image from the modified tree
