Is there available on grub2 a command or function that works this way:

IN: (hd0,1)
OUT: (hd0)

and that also works this way:

IN: (hd0,1)/boot/grub/grub2.cfg
OUT: (hd0)

and also...

IN: (hd0,1,c)
OUT: (hd0)

that we can call hd_from()

?

As you might guess I will use this function in conjunction of search
command to automatise a grub2 reinstallation.

And other similar functions... as isolating the partition part of a given
"grub url" or the slice part ?
