After upgrading grub from 2.12-9 to 2.14-1, I now have
cventin:~> ll /etc/systemd/system/**/*grub*

where /usr/lib/systemd/system/grub-common.service no longer exists.
It seems that symlinks to /usr/lib/systemd/system/grub2-common.service
have been created, but the old symlinks have not been removed.
The installed grub packages:
grub-common, grub-pc, grub-pc-bin, grub2-common.
