Description of problem:
After installing a self built kernel grubby reports a different boot order than what the grub2 menu shows. grubby shows the new kernel as the last boot loader entry vs. grub2 showing it as the first entry.

1. grubby --info=ALL
   index=0

How reproducible:

Steps to Reproduce:
1. install self built kernel "make modules_install ; make install"
2. grubby --info=ALL
3. reboot to see grub menu

Actual results:
grubby and grub2 have a different opinion about the boot entry order

Expected results:
grubby and grub2 have the same order for boot entries
