DHCP issues

I have read several posts and attempted to change the -n option for udhcpc
but apparently I am doing something wrong because when I burn the iso image
after making the change the -n option is still there. It is not in the iso
but is on the client when it fails to boot and I look in the init.d/rcS. I
am using version .7 because I couldn't even find the /etc/init.d in ver .8.
I really like this product and would greatly appreciate any help someone
could give me. Please be specific as to where I should change this.

 

Thanks in advance 

Jim
