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.
