From d136ca4eeb3d7be2beef210dcf51a18210900844 Mon Sep 17 00:00:00 2001
From: Harald Hoyer <harald@redhat.com>
Date: Mon, 8 Apr 2013 17:47:49 +0800
Subject: [PATCH] network: support multiple bonding interfaces
Currently dracut only support 1 bond, namyly bond0 by default. However multiple
bonds configuration may be needed. For example in kdump, in 1st kernel, more
than one bonds may be configured, and bondX other than bond0 is used as output
interface to remote host which will store dump core. This patch can solve this
problem, to write real bond information to initramfs, 2nd kdump kernel will
use it to create the relevant bondX interface.

Subject: [PATCH] Let user specify the action after fail
Currently the default action is emergency_shell when failure happened
during system boot. In kdump, this default may not be expected. E.g,
if dump target is not rootfs, it does not matter if mount root failed.
Adding an action which allow dracut always go ahead though failure
happens is needed by kdump.
So here add a function action_on_fail() and cmdline parameter
action_on_fail=<shell | continue>. Use action_to_fail() to replace
emergency_shell which was called after failure. By $(getarg action_on_fail=),
decide to drop into shell, or to leave away the failure and go ahead.
v3->v4:
add handling of selinux policy loaded failure, and change code format to
be consitent

+**action_on_fail=**_{shell|continue}_::
+ Specify the action after failure. By default it's emergency_shell.
+ 'continue' means: ignore the current failure and go ahead.
