From 0085b2106eb5307ebdae9601471d8387961b2e83 Mon Sep 17 00:00:00 2001
From: Matthew Vernon <matthew@debian.org>

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.)
