Comment 7 for bug 1786699

Hello,

FWIW this breaks the vmdb2 on Ubuntu ("grub: uefi" steps break), and makes it impossible to build uefi bootable Ubuntu images. It would be great to get his merged as a noop, perhaps it would best if the output warned that this is a deprecated flag and is a noop, to discourage its future use, and make sure it eventually goes away when this no longer risks breaking anything.
