A description of how to make Cobbler, PXE, and UEFI behave for Red Hat Enterprise Linux 6 installations

UEFI PXE Installation of RHEL6.4

For some reason, starting a PXE boot installation of RHEL6.4 on UEFI systems is poorly documented. Simultaneously, the process is not terribly verbose when it fails. Here's what I had to do to get this to work.

We going to use Cobbler to take care of a lot of the gruntwork (TFTP, DHCP, etc). It's entirely possible to do it without Cobbler, but even accounting for its warts it will make you more
