From 9f6aded97671ee8b9164f0524b3ac622d827dcde Mon Sep 17 00:00:00 2001
From: Matthew Vernon <matthew@debian.org>
Date: Sun, 9 Feb 2014 16:10:05 +0000
Subject: Include the Debian version in our identification
This makes it easier to audit networks for versions patched against security
vulnerabilities. It has little detrimental effect, as attackers will
generally just try attacks rather than bothering to scan for
vulnerable-looking version strings. (However, see debian-banner.patch.)
