From c299f8584bb1084916ac794a9ebed8324ae4bb10 Mon Sep 17 00:00:00 2001 From: Peter Jones Date: Thu, 23 Jun 2016 11:01:39 -0400 Subject: [PATCH 202/261] Add grub-get-kernel-settings and use it in 10_linux This patch adds grub-get-kernel-settings, which reads the system kernel installation configuration from /etc/sysconfig/kernel, and outputs ${GRUB_...} variables suitable for evaluation by grub-mkconfig. Those variables are then used by 10_linux to choose whether or not to create debug stanzas.
