I updated Tumbleweed to 20151002.

First system - grub distributor = "betasuse".  This went fine.

Second system (different partition on same box) - grub-distributor is empty.

It looks as if grub2-install did write the update to "/boot/efi/EFI/opensuse"
as expected.

However, it looks as if shim-install wrote its update to "/boot/efi/EFI/grub"
which was not expected.  It seems that shim-install doesn't know the new rules
about empty distributor field.

Reproducible: Didn't try
