... or /boot/efi/EFI/centos/grub.cfg if you are booting from an EFI
system.  /etc/grub2-efi.cfg should point at it.  I asked in #centos,
and I think this isn't the location in earlier point releases of
CentOS7.  I don't have an EFI system handy to check.

Grubby is smart about checking both symlinks, in case of EFI.  I kinda
wish it were just one link.
