First entry actually works.  Second does not, but I'm hoping some day it
does.  Probably depends on how grub actually tries to fetches the files,
i.e. whenever the full http url is passed on to ipxe somehow so it can
do its magic.

The file is simply placed as "grub.cfg" in tftproot, next to grubx64.efi

Thanks. From my experiments, it seems that GRUB is using the hardcoded path /efi/boot/grub.cfg to locate the configuration file, regardless of where grub.efi was loaded from.

I can't immediately see where in the GRUB source this path gets derived.
