Bug#695500: debian-installer-7.0-netboot-kfreebsd-amd64: does not boot from pxe

Hi Michael,

Please explain what your setup is, any relevant DHCP config, the TFTP
daemon being used and what sort of client (real hardware with
PXE-capable NIC?).  A screenshot (or even a photo?) of the error message
could be very helpful.

I don't see a problem under Qemu (with iPXE).  But this works a little
differently to pxelinux and this needs to be documented better.

For kfreebsd-amd64 netboot-9, the prefix seems to be hardcoded to
"(pxe)/debian-installer/kfreebsd-amd64/", so as long as I do this:

$ tar -zxvf netboot.tar.gz
./
./debian-installer/
./debian-installer/kfreebsd-amd64/
./debian-installer/kfreebsd-amd64/initrd.gz
./debian-installer/kfreebsd-amd64/kfreebsd-9.gz
./debian-installer/kfreebsd-amd64/grub.cfg
./debian-installer/kfreebsd-amd64/font.pf2
./debian-installer/kfreebsd-amd64/splash.png
./debian-installer/kfreebsd-amd64/grub2pxe
./grub2pxe
./version.info
$ qemu-system-x86_64 -m 256 -enable-kvm -net nic -net
user,bootfile=grub2pxe,tftp=.

GRUB shows me the full graphical menu (grub.cfg and Wheezy splash
artwork are loaded from the TFTP server).

Then I hit a different bug though - it assumes the kernel name is
kfreebsd.gz but for netboot-9 installs this should be kfreebsd-9.gz


I wonder if the 'prefix is not set' error is to do with DHCP options.

Jeff Epler also mentions:
> On the server side, "tftpd 0.17-17ubuntu1" doesn't seem to work, while "tftpd-hpa 5.0-11ubuntu2" does. The symptom is that grub can't find grub.cfg.
