I would be very interested in seeing your code.

Can't get away, from that, but you can automate it several ways.

1) pxe  You can specify your ks option as part of a pxe invocation.
ie..
	[root at hross pxelinux.cfg]# cat base.cfg 
	prompt=0
	label linux
        kernel vmlinuz-34
		append rw load_ramdisk=1 prompt_ramdisk=0
		ramdisk_size=16384 initrd=initrd-34.img
		ks=http://10.8.80.254/centos34/base-ks.cfg vnc

	(the last three lines have to be a single line)
	Go here http://www.owlriver.com/tips/pxe-install/ for a short
	cookbook on doing pxe.  Also here

2) You can modify isolinux.cfg on a boot cd so the default stanza has
the correct invocation

3) If you are rebuilding boxes, pull the initrd.img and vmlinuz off of
boot.iso and create an rpm that has a %post script that uses grubby to
add the correct info to /etc/grub.conf

Here is a %post section...

%post
/sbin/grubby --add-kernel=/boot/rh3boot.vmlinuz \
        --initrd /boot/rh3boot.initrd.img \
        --args "console=ttyS0,tty0 ks=http://10.129.7.209/ksbase/ksconf.php?type =rhas30u3as" \
        --title "Red Hat 3 install ($version)"

/sbin/grubby --add-kernel=/boot/rh3boot.vmlinuz \
        --initrd /boot/rh3boot.initrd.img \
        --args "ks=nfs:10.128.138.253:/nfsserver/lrh3/installdb/lrh3-u3-ks.cfg" 
\
        --title "Red Hat 3 install ($version) test"
