grub2-mkconfig warning please don't use old title

[Chris Murphy]

I'm getting this on a clean Rawhide UEFI install, which includes grub2-2.02-0.6.fc21.x86_64.

[root at localhost ~]# grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg

Is this a grubenv problem? The grub default is saved, not specified, in /etc/default/grub, so I'm not sure where else grub2-mkconfig might be picking this up. Is it possible the recent change to the default is causing this?

Since this is UEFI, grub2-install isn't called, so what's creating grubenv? Is grubby creating/modifying grubenv?

 # dnf provides grubenv
Error: No Matches found

[root at localhost grub2]# grub2-editenv list
saved_entry=Fedora, with Linux 3.16.0-0.rc3.git2.1.fc21.x86_64

Looks like the grub.cfg tells grubx64.efi to save this out to grubenv at boot time. Hmmm… the warning doesn't seem right even though everything works as I'd expect.
