Great! Then you can try running the kernel package's %posttrans scriptlet
commands manually and try to determine which part fails. Here it calls
the kernel-install shell script:
# rpm -q --scripts kernel|tail -2
posttrans scriptlet (using /bin/sh):
/bin/kernel-install add 3.12.5-302.fc20.x86_64 /boot/vmlinuz-3.12.5-302.fc20.x86_64 || exit $?

/etc/sysconfig/grub is the file to edit, since grub.cfg may be overwritten
(e.g. when running grub2-mkconfig), and if you are not careful when
editing the symlink, it will be replaced with a file and disconnected from
# file /etc/grub2.cfg
/etc/grub2.cfg: symbolic link to `../boot/grub2/grub.cfg'
