File kdump-include-hosts-and-nsswitch-in-kdumprd.patch of Package kdump

From: Roberto Sassu <rsassu@suse.com>
Date: Fri Sep 16 19:57:05 2016 +0200
Subject: Refresh kdumprd if /etc/hosts or /etc/nsswitch.conf is changed
References: bsc#943214
Patch-mainline: v0.8.16
Git-commit: e727e727bb9471b8efe602193a4d71930728d75e

These files may be necessary to resolve the dump target host, so let's
include them in the initrd, and also update the initrd image if they
are changed.
