Can I append a ks= within isolinux.cfg?

[zoomtard]

I am trying to make a custom boot disk which allows the user to install Fedora via kickstart over nfs. I've tested the kickstart portion already and it works flawlessly. While preparing to make an .iso, I edited isolinux.cfg like so:

default linux
prompt 1
timeout 600
display boot.msg
F1 boot.msg
F2 options.msg
F3 general.msg
F4 param.msg
F5 rescue.msg
F7 snake.msg
label linux
  kernel vmlinuz
  append initrd=initrd.img ramdisk_size=8192
label fed4
  kernel vmlinuz
  append ks=nfs:xxx.xxx.xxx.xxx:/var/distros/Fedora/ks.cfg initrd=initrd.img ramdisk_size=8192

When I boot from the disc and type 'fed4' at the prompt, it goes into a normal install. I think it might be ignoring the ks= option I added to append. Is there a way to append the ks= option without having to type it at the prompt?

I changed the ks line to ks=cdrom:/ks.cfg and it worked flawlessly. I guess it tried to look for the nfs server over the network before it could get an IP assigned.
