Hello,

Here are the steps which I follow to modify my ISO for adding Kickstart,
you might want to give it a try. One can run these steps on RHEL7/CentOS7
machine.

1. Mount the DVD iso at some location:

    # mount -o loop /path/to/rhel-server-7.2-x86_64-dvd.iso /mnt

2. Then create a directory and copy all the contents of the ISO into the
same.

    # mkdir /tmp/rhel7
    # shopt -s dotglob
    # cp -avRf /mnt/* /tmp/rhel7

3. Verify that all hidden files like .treeinfo are there in /tmp/rhel7

    # cd /tmp/rhel7
    #  ls -a

4. Get the kickstart file and rename it to ks.cfg

    # cd /tmp/rhel7
    # wget ftp://192.168.122.254/rhel7/ks.cfg <========== or simply copy
your kickstart file

5. Confirm the LABEL of the DVD iso.

    # blkid /path/to/rhel-server-7.2-x86_64-dvd.iso

6. Add the stanza in /tmp/rhel7/isolinux/isolinux.cfg file as follows.

#######################################
label kickstart
  menu label ^Kickstart Installation of RHEL7.2
  kernel vmlinuz
  append initrd=initrd.img inst.stage2=hd:LABEL=RHEL-7.2\x20Server.x86_64
inst.ks=cdrom:/ks.cfg
#######################################

Make sure that the stanza has inst.stage2 and the correct label.

7. Now, save the file and create the ISO as follows.

    # mkisofs -J -T -o /tmp/rhel7test.iso -b isolinux/isolinux.bin -c
isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -m
TRANS.TBL -graft-points -V "RHEL-7.2 Server.x86_64" /tmp/rhel7/

The ISO /tmp/rhel7test.iso will be bootable. This will be for Legacy Boot
only, for UEFI boot, the procedure will be a little bit different. Just few
more steps added/replaced.
