[Bug 2130774] Re: chainloader fails due to peimage.

[Mate Kukri]

It is normal in the sense that GRUB always had this weirdness, but it
was never a problem for Debian or Ubuntu due to how the config works.

It would be nicer if this wasn't an issue but deriving the device path
from explicitly set root is easier, because GRUB can load EFI images
from a lot of targets that are not visible to the firmware (e.g. LVM,
LUKS and so on)
