Maybe things have changed in 5.x but I recall some annoying issues
with having a USB device plugged in during kickstart as the kernel
would sometimes map that device as sda and that could screw up my
partitioning scheme. I think it would be easier to put the kickstart
file on the DVD and have a different DVD for whatever purpose you
want, unless you anticipate needing to change the kickstart file
frequently.

Same goes for having external SCSI or fiber channel devices connected
during kickstart, I always disconnect all block devices other than
the boot device whenever possible when using kickstart.

That is assuming your looking for a fully automated installer, vs
loading kickstart with minimal configs and doing a bunch of manual
work during installation.
