[syslinux] Loading files from another tftp server

[Erwan]

Hi,

I run Pxelinux for ages on my cluster without troubles, I have to say... 
that's a great project.
I'm facing a new challenge that I don't really know how to solve it. 
That's a mission for pxelinux :o)

My pxelinux and my kernels/initrds are stored on the same tftp server.
Now I'd like to tweak the next-server field of the DHCP answer and then 
reload another bootstrap from another tftp-server.

How can I achieve that ?
Thanks,
Erwan
