Package: grub-efi-amd64
Version: 2.02+dfsg1-6
Severity: important

Dear Maintainer,

I installed a vanilla Debian Testing on XFS on my KVM server. I adjusted
the proposed whole disk layout to use XFS instead of ext4 during the
installation. I ended up with a eps, XFS and a swap setup, one that
worked well with Jessie and Stretch. After finishing the installation, I
rebooted and fell back to the Grub cmd prompt. 

After investigating the issue, I found out that no xfs.mod was loaded. I
then manually copied /boot/grub/x86_64-efi to /boot/efi/EFI/debian,
since /boot/grub is not accessible at this stage. This worked, my system
boots now. 

I compared this with an identical Stretch setup. In Stretch, everything
works fine without a /boot/efi/EFI/debian/x86_64-efi folder. 

Please notice that this was made in a KVM/UEFI Setup under Stretch.

Thank you very much.
