Ub 16.10 - grub writes invalid search entry in grub.cfg

[BobDodds]

Description: Ubuntu Yakkety Yak (development branch)
Release: 16.10
grub-efi_2.02~beta2-36ubuntu10_amd64.deb
grub-efi-amd64-signed_1.73+2.02~beta2-36ubuntu10_amd64.deb
grub-efi-amd64-bin_2.02~beta2-36ubuntu10_amd64.deb
grub-efi-amd64_2.02~beta2-36ubuntu10_amd64.deb

I had InsydeH20 setup "load file", grubx64.efi.signed, and at the grub prompt I tested search, search.fs_uuid, search.fs_file, and search.label. The old search line in grub.cfg is a bug!

You will not notice anything wrong in the result, if at grub prompt you search with the expectation of seeing (hd0,msdos1) because search will always echo that default back to you as if it did a search, when it did nothing. Try looking for uuid/file/label for (hd0,msdos2) or another partition number higher than the first partition. Broken!

All of these "search --nofloppy" grub.cfg lines are broken in several different ways including the "=" not working anymore:

search --nofloppy --fs-uuid [uuid] --set=root

the new, working syntax goes like this:

search -n -u [uuid] -s root

That's the bug. 16.10 64-bit just installed grub and Ubuntu nicely in efi mode, then reboot bsod due to the bad search line in grub.cfg.
