sudo /bin/kernel-install add
3.12.5-302.fc20.x86_64 /boot/vmlinuz-3.12.5-302.fc20.x86_64 || exit $?
grubby fatal error: unable to find a suitable template

I looked around, but almost all the discussion on the web seems to be
circa 2011 when grub moved to grub2 so I am not sure that these seem
relevant. (In any case, most of them say run grub2-mkconfig but I was
trying to get a more long-term solution.)

I guess I am trying to learn by taking the first step of finding the
process of getting to it? Hence the questions. Perhaps the background
needed is too much to figure out on one's own. 

Thanks for your time and patience, though!
