From b258a00bedcf29200b394c671c6deb1e53157f32 Mon Sep 17 00:00:00 2001

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.)
