Description of problem: Reinstalling a kernel that is already installed (e.g. - yum reinstall kernel-3.10.0-123.el7.x86_64) has created a second copy of the kernel to appear in the grub menu. It also caused https://bugzilla.redhat.com/show_bug.cgi?id=1124074 to affect my system, but that's a separate problem.
Version-Release number of selected component (if applicable): grub2-2.02-0.2.10.el7.x86_64
How reproducible: Every time
Steps to Reproduce:
1. Have at least two kernels installed
2. yum reinstall kernel-3.10.0-123.el7.x86_64
3. Look at /etc/grub2.cfg, or reboot and look at menu, etc.
Actual results: Reinstalled kernel appears in grub menu twice.
Expected results: Should only appear once.
