Subject: [PATCH] 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.
Resolves: rhbz#1226325
