Bug#926178: grub2 efi boot installs grub.cfg file that seems to be ignored (just stays at prompt)

[Norbert Lange]

Package: grub2
Version: 2.02+dfsg1-16
Severity: important

Hello,

setting up some new systems I ran into the issue that
newer versions of grub-install will place multiple
files into /boot/efi/EFI. One among them is 'grub.cfg'
which tried to set 'root' by searching for the UUID,
then loading the real boot/grub/grub.cfg.

It appears to me, that is file is never used, as
grub just drops to the prompt without any notification.

The older version 2.02+dfsg1-4 is installing a single file,
and boots correctly.
