Message-Id: <200904012144.13077.elendil@planet.nl>
Date: Wed, 1 Apr 2009 21:44:11 +0200
From: Frans Pop <elendil@...net.nl>
To: linux-kbuild@...r.kernel.org
Cc: linux-kernel@...r.kernel.org, Sam Ravnborg <sam@...nborg.org>
Subject: [PATCH 5b/5] deb-pkg: allow alternative hook scripts directory in .deb packages
Hook scripts in the default directory /etc/kernel are also executed by
official Debian kernel packages as well as kernel packages created using
make-kpkg. Allow to specify the base hook scripts directory in the kernel
configuration (DEB_HOOKDIRS_PATH).
