From ddf482232a47f5d2db9b3d40d89ee4094a6ac936 Mon Sep 17 00:00:00 2001 From: Peter Jones Date: Wed, 22 Jun 2016 14:07:49 -0400 Subject: [PATCH 50/55] 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.
