[Dnsmasq-discuss] Would like to use dnsmasq for cluster booting

Hi folks:

   I have been using dnsmasq for a few years within a simple network and 
some linux clusters.  With the inclusion of the DHCP bits, and the bootp 
bits, suddenly the idea of replacing that fine bit of work known as the 
ISC DHCP server seems possible (and quite likely).

   I have managed to serve some pxelinux.0 files quite nicely.  What I 
want to do is to serve the nbgrub (network boot grub) bits, and have it 
read its menu.lst.

   To make this happen, I need to set option T150 to (nd)/menu.lst .  I 
am doing this via

	dhcp-option=150,"(nd)/menu.lst"

   So after setting this up, nbgrub does boot, but the logs have

Sep  3 07:40:55 autoinst dnsmasq[11915]: DHCPREQUEST(eth0) 192.168.32.34 
00:11:09:cc:d3:e8
Sep  3 07:40:55 autoinst dnsmasq[11915]: DHCPACK(eth0) 192.168.32.34 
00:11:09:cc:d3:e8
Sep  3 11:40:55 autoinst in.tftpd[11946]: RRQ from 192.168.32.34 
filename /nbgrub
Sep  3 11:40:55 autoinst in.tftpd[11946]: tftp: client does not accept 
options
Sep  3 11:40:55 autoinst in.tftpd[11947]: RRQ from 192.168.32.34 
filename /nbgrub

   and then nothing (e.g. no menu.lst request), and the grub just hangs 
there.

   What am I doing wrong?  Will dnsmasq work this way or can it serve 
only pxelinux like bits?

   Here are my relevant dnsmasq.conf options:

	domain=boot.scalableinformatics.com
	dhcp-range=192.168.32.1,192.168.32.128
	dhcp-boot=/nbgrub,autoinst,192.168.32.217
	dhcp-option=150,"(nd)/menu.lst"

   Thanks!

Joe
