I've modified somewhat a work of vagrantc's, and I've made a package
that adds a gPXE (Etherboot) entry to the grub2 menu, by:
* Putting the Etherboot "all-drivers" kernel to /boot/gpxe.lkrn
* Creating an /etc/grub.d/41_gpxe grub2 script
* Calling update-grub
So if anyone has Ubuntu Karmic or

We're using *only* the router's DHCP server, in tens of labs. It's been

It is possible, but you'll need some serious initramfs hacking (putting
your wireless driver there, probably even putting the WPA keys etc).
Can't help there, never done it.

That's the way grub2 wants the grub.cfg entry, yup, nothing critical.
For reference, here's how I do it on grub2.
Grub2 discourages manual editing of grub.cfg, and uses scripts instead.
So I create a file named /etc/grub.d/41_gpxe with the following contents:

exec tail -n +3 $0

Etherboot is deprecated in favor of gPXE, from the same team.
Also, the nbi.img images that are used by the older etherboot versions
have some problems in Ubuntu Karmic. IMHO, gPXE is the way to go.

from the following site:

After removing udhcpc, don't forget to also update the kernel, i.e.
`update-initramfs -u` in the chroot, and
`ltsp-update-kernels` outside of the chroot.
`ltsp-update-image` is NOT needed.
If you want, you may visit #ltsp at irc.freenode.net for live help on
the problem...

If it didn't, maybe it's not declared correctly.

The alternate cd should have put a static IP for eth1 in
