Subject: [PATCH 5b/5] deb-pkg: allow alternative hook scripts directory in .deb packages
Date: Wed, 1 Apr 2009 21:44:11 +0200
Message-ID: <200904012144.13077.elendil@planet.nl> (raw)
In-Reply-To: <200904012133.37387.elendil@planet.nl>

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).
