Comment # 2 on bug 973751 from Michael Chang

As far as I know, ubuntu grub2 did not verify their kernel image or even do not
sign their kernel, but it's from their initial work of uefi secure boot support
and things may have changed.

But anyway, we got hit by issues of such different shim instances from time to
time. Reassign to Gary as he's now maintainer of it.

Thanks.
