Dropping super-user requirement would be useful. You can build rescue
CD using grub-mkrescue that does not require any root and QEMU itself
certainly does not require it. 

Oh, and many ditros install new grub as grub2. I tried it on openSUSE:

cp: невозможно создать обычный файл 
«/home/bor/src/grub2-theme-preview/3a3b931c4be83230c53f444e83e1d4935fe99ead099f8a3b7679f6ad8592f3d8/boot/grub/grub.cfg»:
 Нет такого файла или каталога

(No such file or directory)

which is correct

address@hidden:~/src/grub2-theme-preview> LC_ALL=C ll 
3a3b931c4be83230c53f444e83e1d4935fe99ead099f8a3b7679f6ad8592f3d8/boot/
total 13
drwxr-xr-x 5 root root  1024 Feb 11 09:27 grub2
drwx------ 2 root root 12288 Feb 11 09:26 lost+found

Yet another reason to use grub-mkrescue which is always using fixed
path /boot/grub on CD image.
