Dear Maintainer,

Trying to launch EFI netboot images on clients using working described
method :
https://wiki.debian.org/PXEBootInstall#Simple_way_-_using_Dnsmasq but
with Dnsmasq set as a proxy of another DCHP server.

The described method works as expected if Dnsmasq is set as a real DHCP
server. But if we use Dnsmasq as a DHCP proxy server it won't work for
EFI images (it works for BIOS images).


If you replace the line "
dhcp-range=192.168.0.3,192.168.0.253,255.255.255.0,1h "

with " dhcp-range=192.168.0.0,proxy,255.255.255.0 ", the Grub install
menu is not prompted for EFI images (it is for classical Bios images on
older targets but not for EFI images).


Actual results :


Instead of a Grub Install menu, an empty black grub shell is prompted.


Expected results :


A Grub Install menu is prompted for EFI netboot images, as it is when
Dnsmasq is a real DHCP server and not a proxy.
