Bug Description

Ubuntu Desktop/Server 17.10.1 allows manual partitioning of a disk and the selection of a non-ext{3,4} filesystem for the / partition. The grub2 uefi module (at least the amd64 one) is not baked with support for all the filesystems that one can deploy Ubuntu during setup. Result: grub2 is installed and runs after reboot, but errors out before it can load the kernel as it has not been baked with support for the filesystem in question.

Tested against an xfs root partition on both physical and virtual hardware.

Somewhat like #185878, only affecting UEFI instead of MBR installations.

Triaged:

xfs is clearly not on the list of modules included in signed images, and there's a very solid point in making sure the images we ship include all the filesystems we support at install time (zfs is even listed).

Changed in grub2 (Ubuntu):
