Hi Al,

I can't say I've setup a 'proper' netboot system, but when I was doing
my bringup for the X5000 (and writing that wiki page) my netboot
consisted of a isc-dhcp server and a tftp server with the kernel and
dtb files.  The kernel at the time was a uImage, as demonstrated on the
wiki page.  However, now it's possible (and I strongly encourage) to
use ubldr to boot the kernel.  I will update the wiki page as soon as I
get the last piece of the puzzle committed for placing ubldr in the
right place at install time.

An alternative would be to create a release image (make buildworld
buildkernel KERNCONF=QORIQ64 TARGET_ARCH=powerpc64; make -C release/
cdrom TARGET_ARCH=powerpc64), put that image onto a USB stick and
"netbooting" ubldr (put ubldr on a tftp server, and boot that), and
setting the loader to boot from the USB stick.  You might be able to
just boot straight to ubldr on the USB stick, too.
