Bug#519999: mdadm: Init script calls modprobe with argument it no longer recognizes

Package: mdadm
Version: 2.6.8-12-gb47dff6-2
Severity: important
Tags: patch
After recent upgrade, mdadm stopped working for me. The modules did not
load and thus array was not assembled. Manual inspection revealed, that when
modprobe is called as:
modprobe -kq md
from /etc/init.d/mdadm-raid, it complains about unrecognized option -k and
does nothing.
People who have root on md device are not affected, because the script used
in initramfs does not specify that option. Attached patch removes -k option
from all invocations of modprobe I found in the package. The one in
mdadm-raid was the one that hit me.
Since there was no upgrade of mdadm, but there was upgrade of
module-init-tools, I am CC'ing it's maintainer. I leave it up to you to
consider whether modprobe should silently ignore -k for compatibility with
legacy scripts.
Because I use etckeeper, I can tell you the packages I upgraded between last
successful and today's unsuccessful boot:

--- I have reinstalled the package while trying to find the root of the
problem. During that, the package configuration step regenerated the
mdadm file. First the new version, than the original. Unfortunately,
I can't similarly compare the initrd content, because that is not
versioned by etckeeper.
