If GRUB's prefix is on an encrypted disk, it prompts for a passphrase for the disk. I have an i386 machine without a monitor and without a BIOS that can use the serial port as a console and want GRUB to display its prompt and read the passphrase from a serial port. Since grub.cfg is not loaded without the passphrase the serial port configuration would have to be embedded into the core image.
grub-install does not allow to customize the configuration, so I created an image via grub-mkimage with the parameters grub-install generated a simple serial port configuration similar to the example in the manual that works within grub.cfg. Unfortunately it didn't work when embedded into the core image. Is it possible to embed serial port configuration in the core image? If so, how do I do it? Are there plans to support custom embedded configuration in grub-install? If not, would patches be accepted? I don't want to manually regenerate the core image after each GRUB update when the package manager runs grub-install overwrites a core image with the embedded configuration.
