From 8efba98644f9262d74a42fac7ea39d197192443a Mon Sep 17 00:00:00 2001
From: Peter Jones <pjones@redhat.com>
Date: Wed, 22 Jun 2016 14:07:49 -0400
Subject: [PATCH 20/55] grubby: add --set-index to specify which position to
add new entries as
This adds an option, "--set-index N", to grubby, and will cause creation
of any new entry to be at a particular zero-indexed position in the
resulting configuration file.
Related: rhbz#1285601
