Shouldn't the init script do that?

It is there when I chroot into the target system.

That could it be. I didn't even find what deletes this file.

Right, take the drive anf put it into another machina whetre it'll be
the first HD.

To test this GRUB on (hd2) could be chain loaded using GRUB on (hd0).

Nope, /boot is on the first partition of the HD.
