Grub partition, as I'm taking it, means: MBR gap on MBR layouts; and BIOS Boot partition (GUID 21686148-6449-6E6F-744E-656564454649) on GPT layouts. In any case, MBR gap, dedicated GPT partition, or grub.efi application, it's possible to bake a grub.cfg directly into the core.img. Technically using configfile is not chain loading, you're just having the same instance of GRUB load an alternate config. Chain loading GRUB implies loading a new binary (boot loader) to replace the first instance of GRUB. Using configfile has the caveat that the GRUB using configfile may be of a different version than the GRUB package that produced the grub.cfg being configfile loaded. And as the syntax of grub.cfg has been changing quite a bit it's possible to have related failures.
