From 421419c7fc96df18c422102a52879dd6860725a6 Mon Sep 17 00:00:00 2001
From: Daniel Baumann <mail@daniel-baumann.ch>
Date: Mon, 10 Aug 2015 21:31:17 +0200
Subject: Getting rid of hard-coded release numbers and using /etc/os-release
 instead (Closes: #790860).

Unfortunately VERSION_ID on testing/unstable is currently not included
in /etc/os-release, see #795124.
