Re: [Fwd: Added "stage2-diskless" build]

I have not seen the current implementation of you,
as I did not make a CVS CHECKOUT for a month or so. 

The reason why I did the patch was: The preset menu
"must" be executed before the the network setup is
done. It is really important for me (and for many embedded
users), that the preset menu is executed before the
network stuff is initialized, otherwise GRUB may hang and
the user is blind !

The only alternative way, I see for this point, is to
have a straight way to define a console (screen/keyboard,
serial+config) to have an active console. (I also miss
GEOM Error, etc on the serial console, but I see, the 
BIOS is also not directed to the seriel console, so
we forget this point). But the network setup is 
important here ....

So my primary goal was not to have the preset menu
executed before the main menu, but I want to have
a method to setup the serial console via preset menu
and to do the rest of the jobs after that (network
setup and main menu) without breaking your concepts,
the the menu items of the preset menu and config
stuff of the preset menu are overridden by the main menu.

With friendly regards
