I want `ks.cfg` on dvd itself to keep everything at same place.

Content of `isolinux/isolinux.cfg`

```
label ks
  menu label ^Kickstart
  kernel vmlinuz
  append initrd=initrd.img ks=cdrom:/ks.cfg

```

And `ks.cfg` is on top `/` of cdrom.
but when actual installation starts it says disk not found in any of cdrom.
I am creating iso with following command, 

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

```

I tried with creating new dir `/ks/ks.cfg` but it is also not working
