Drew, it really depends on what you want to do.  What I do is stage all my
build content on the network.  So my USB image has syslinux, vmlinuz,
initramfs and my ks.cfg.

I reference all I want to do via my ks.cfg.

If I'm doing a generic DHCP build, even my (generic) ks.cfg will be on the
network.

Because boot media size is of great concern for us, we have a minimal boot
USB media.  It's
39 MB for OL6.5.  We have a larger boot media, that will allow you to
install anything from RHEL 5.4 up to RHEL 6.5.

If this is of interest to you, drop me a note and I'll send doc with full
instructions.

PS For RHEL7 static builds, while good in other ways -- the new anaconda
results on the squashfs.img having to be on USB. So the absolute min-sized
USB boot media is ~250 MB.
Ouch!
