dracut/grubby fails to update grub.cfg

[Stefan Huchler]

When I update to a new kernel with dnf or yum, it
installs it, creates a working initramfs file like it should, but it does
not update grub.cfg in /boot/grub2/ . 


I see following error:

grubby fatal error: unable to find a suitable template

when I do then:

sudo grub2-mkconfig -o /boot/grub2/grub.cfg

all works fine but I have to do that on each kernel update.

System Fedora Core 20   x86_64
