File kdump-bootloader-grub2.patch of Package kdump.624

Date: Fri Sep 26 11:43:33 2014 +0200
From: Petr Tesarik <ptesarik@suse.cz>
Subject: kdump-Bootloader: add support for GRUB2
References: bsc#889192
Patch-mainline: v0.8.16
Git-commit: 30d4271c72251c5f1c995d0580b19aa000ade1d6

GRUB2 is very different from the other bootloader, because the final
configuration file is generated by an external utility. This means
that the command line must be modified in the global settings instead
of the individual section.
