// Unattended-Upgrade::Origins-Pattern controls which packages are
// upgraded.
//
// Lines below have the format format is "keyword=value,...".  A
// package will be upgraded only if the values in its metadata match
// all the supplied keywords in a line.  (In other words, omitted
// keywords are wild cards.) The keywords originate from the Release
// file, but several aliases are accepted.  The accepted keywords are:
//   a,archive,suite (eg, "stable")
//   c,component     (eg, "main", "crontrib", "non-free")
//   l,label         (eg, "Debian", "Debian-Security")
//   o,origin        (eg, "Debian", "Unofficial Multimedia Packages")
//   n,codename      (eg, "jessie", "jessie-updates")
//     site          (eg, "http.debian.net")
// The available values on the system are printed by the command
// "apt-cache policy", and can be debugged by running
// "unattended-upgrades -d" and looking at the log file.
//
// Within lines unattended-upgrades allows 2 macros whose values are
// derived from /etc/debian_version:
//   ${distro_id}            Installed origin.
//   ${distro_codename}      Installed codename (eg, "jessie")
