Bug#928750: [grub-efi-amd64] On EFI pxeboot grubx64.efi only loads config when loaded directly

Fri May 10 10:37:55 BST 2019

Package: grub-efi-amd64
Version: 2.02+dfsg1-16
Severity: important

--- Please enter the report below this line. ---

https://d-i.debian.org/manual/en.amd64/ch04s05.html mentions that you need to 
configure
  filename "debian-installer/amd64/bootnetx64.efi";
as bootfile for booting via PXE in dhcp configs.

When doing so, grubx64.efi will be loaded in the next step, but will not try
to load its config files and - after 30s wait time showing the attached screen on console
present the Grub shell.
(As mentioned in https://lists.debian.org/debian-boot/2019/05/msg00076.html)

Excerpt from logs:

(Nothing re tftp afterwards)

If you change the boot option in dhcp. conf to
  filename "debian-installer/amd64/grubx64.efi";
it changes to:

After adding a symlink in /var/lib/tftpboot/ grub -> debian-10/debian-installer/amd64/grub
(additional to debian-installer -> debian-10/debian-installer), Grub will load and we can chose a menu
to start our preseeded install:
