Download the file CentOS-6.2-x86_64-netinstall.iso

Create make.sh:

VERSION=$1
TYPE=$2
KS=ks-$VERSION-$TYPE
ISO_NAME=centos-$KS.iso

set -x

if [ -d bootiso ]; then rm -rf bootiso; fi
if [ -d bootisoks ]; then rm -rf bootisoks; fi
mkdir bootiso
mkdir bootisoks

mount -o loop CentOS-$VERSION-x86_64-netinstall.iso bootiso

cp -r bootiso/* bootisoks/

umount bootiso

cd bootisoks/

cp ../$KS.cfg isolinux/ks.cfg
cp ../isolinux.cfg isolinux/

mkisofs -o ../$ISO_NAME -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T isolinux/
