Running the preset option more than once

[Damian Ivereigh]

Hi guys, 

I think this is a bug, but would like it confirmed. I set the preset
menu/config (i.e. the menu compiled into grub) to be "bootp
--with-configfile" - this is an extension of the diskless setup. The
idea being that once grub starts it will automatically get a bootp/dhcp
address and then run the config file specified in the T150 tag of the
bootp response. 

This all works until it comes to execute the new config file: it re-runs
the preset menu/config, which of course issues another bootp and get
another config file, endless loop. 

I have enclosed a patch that will fix this by checking the return value
from the setjmp, such that if it is not the first time through, it
"closes" the preset menu, which turns it off. However maybe there is
some other way to do this.

Thoughts? 

Damian
