I'm trying a PXE/kickstart off our mirror of SL4/RC2.5: the stage2
installer craps out with the unispiring warning that 

	"The Scientific Linux installation 
	tree in that directory does not seem 
	to match your boot media".

I've seen this before when I accidentally mixed up some install media.

Our PXE/Kickstart system has the latest 40rolling and I've copied the
images/SL/pxeboot/vmlinuz and initrd.img into the PXE system.

Am I missing something or is there a fault in RC2.5?

Martin.
