grub2 vs. kexec

[Michael Reichenbach]

With great interrest I was reading http://grub.enbug.org/GSoC/Ideas2009
the new ideas sound really innovative.

I see two possible approaches to implement such features. Either
- doing it the GRUB2 way or
- loading a linux kernel (which supports already all the stuff), loading
the needed drivers (bluetooth for menu, wlan and tcp/ip for network
booting) and use kexec to boot the the new kernel

I mean you are going to implement almost a complete operating system
again for booting another operating system. At the same time there is
already a complete operating system (linux) which is also able to boot
another operating system (kexec).

What is the advantage of the GRUB2 way?
