Ah. Apologies, you've clearly found a bug in our setup. :-(
It looks like what you're seeing is that the signed grub image is
using a different $prefix setting, and now it needs help to find the
grub.cfg file.
The debian-installer build used to rebuild its own grub EFI image and
change some config during that build (using -p
"$netboot_prefix/grub"), but now we can't do that (as it would lose
the signature). We need to update our netboot tree and the
documentation to reflect this.
