Kickstart from FTP or USB

[centos-list at unassemble.co.uk (Lee W)]

Hey Everyone,

I was wondering if anyone has managed to do a network install where the 
kickstart file is located either on an FTP site (which is also where the 
packages are stored) or on a USB flash drive.

I've tried starting the installer with "linux ks=/dev/sda/ks.cfg" or 
"linux ks=/dev/sda1/ks.cfg" or "linux 
ks=ftp://what.ever.Ip.address/pub/ks.cfg"; but when the installer starts 
I just gen error (something) like "null: bad address.

I've checked the RH docs and it seems that at the very least the USB 
method should work.

Thanks in advance

Regards

Lee
