Package: grub-efi-amd64-signed
Version: 1+2.12-9+deb13u2
Using "grub-install --force-extra-removable" it seems the BOOT entry written to
/boot/efi/EFI lacks a grub.cfg file. It doesn't boot. I just get a grub prompt
at boot time. Example:
# rm -rf /boot/efi/EFI/*
# grub-install --recheck --efi-directory=/boot/efi --bootloader-id=usbpc
--force-extra-removable
# find /boot/efi/EFI -ls

If I generate the regular boot entry using a dedicated boot loader id and the
"removable" BOOT entry in 2 steps, then it works as expected:
# rm -rf /boot/efi/EFI/*
# grub-install --recheck --efi-directory=/boot/efi --no-nvram --removable
# find /boot/efi/EFI -ls
