      My experience with grubby being run after kernel installs, when I

grub.cfg file. For example, I have been in the situation where the boot

'Advanced Fedora Options' (or something similar) along with the same
structure for Ubuntu, then after running grubby, the groupings were
removed and all the entries that were listed in the groups were moved to
the top level.
Can't confirm.

These are the steps I've tested with on Fedora 20:

1) In /etc/default/grub I've set

   GRUB_DISABLE_SUBMENU=false

2) I've run  "grub2-mkconfig -o /boot/grub2/grub.cfg"  to create the
   grub.cfg with submenus.

3) I've saved grub.cfg as ~/grub.cfg.MKCONFIG

4) I've run  "yum --enablerepo=rawhide install kernel"  to add the kernel
   package from Rawhide.

5) I've run  "diff -u ~/grub.cfg.MKCONFIG /boot/grub2/grub.cfg"  to display
   the differences.

What has changed in grub.cfg?

  * a new "menuentry" block for the new kernel at the top
  * removed trailing whitespace at the end of "linux" lines
  * replaced double-quote characters with single-quotes in menuentry blocks

Upon  "yum history undo …"  only the added menuentry block was removed
again.
Looks like grubby has changed since the last time I used it, it is now 
creating sub-entries as well. I'll need to now check if I still get the 
same problem on kernel updates where grubby fails with an authorization 
failure even though the update process is run under sudo, but when I run 
grubby manually under sudo it runs fine.
