grub2 bug and question

[Sergey Matveychuk]

Hello.

I've begun work with grub2 sources. There is some progress.

I've found a bug:
util/pupa-emu.c:main() - grub2 can't guess a root device because 
pupa_guess_root_device() called before pupa_util_biosdisk_init().

pupa_guess_root_device() use map[] before it's filled in 
pupa_util_biosdisk_init().

Question: it's looks like a root command get only disk name (root (hd0)) 
and don't understand old syntax: root (hd0,1,a)?
