-# TODO combine 10periodic and 20auto-upgrades
+# The next two files share a source file. Different packages manage
+# each of these and we do not want them to get out of sync with each
+# other as that can impact the configuration that apt sees based on
+# priority rules. We address this by making the two files have the same
