Package: grub-efi-amd64
Version: 2.12-1~bpo12+1
Severity: normal
X-Debbugs-Cc: p.f.j.geraedts@gmail.com

Dear Maintainer,

As bootloader I use GRUB standalone (from memdisk) portable. To reach the (1st)
grub.cfg file I use the cmdpath environment variable that GRUB offers [1].
Before, in case of GRUB 2.06-13+deb12u1, its output was as expected:
I expect "(hd0,gpt1)/EFI/BOOT". Now, in case of GRUB 2.12-1~bpo12+1,
its output is empty. I regard this as a regression.
I can confirm that the latest compiled GRUB source from git (GRUB 2.13)
works as expected. Thank you in advance for your time.

Devuan doesn't fork src:grub2 and uses Debian's packages directly without
recompilation. This issue appears to be the same as Debian #1099191. Please add
your voice there to get it resolved.

Thanks

Mark
