From 4062ab33c8cd86ac15cefe1b4f2f422b28467f54 Mon Sep 17 00:00:00 2001

Subject: [PATCH] grub-mkconfig.in: turn off executable owner bit
Stricker permissions are required on the grub.cfg file, resulting in
at most 0600 owner's file permissions. This resolves conflicting
requirement permissions on grub2-pc package's grub2.cfg file.
