        Although a lot of people want you to begin with the second option and
although it's a good thing for an hipothetical super grub2 disk... I
want to remind you what's the okuji thought about this:

Nope. This is a different thing. This is a new feature which is not
present in GRUB Legacy.

Although people often mistake this, booting a CD from GRUB is quite
different from booting a GRUB installed into a CD. GRUB Legacy has the
latter feature, but not the former one.

GRUB 2 needs to support both cases, but I prefer to see something not
present in GRUB Legacy implemented in GRUB 2 first.

But do as you want, maybe it is better to begin with the easiest task
and then doing the more difficult task.
