+# Default behavior for the release upgrader.
+[DEFAULT]
+# Default prompting behavior, valid options:
+#
+#  never  - Never check for a new release.
+#  normal - Check to see if a new release is available.  If more than one new
+#           release is found, the release upgrader will attempt to upgrade to
+#           the release that immediately succeeds the currently-running
+#           release.
+#  lts    - Check to see if a new LTS release is available.  The upgrader
+#           will attempt to upgrade to the first LTS release available after
+#           the currently-running one.  Note that this option should not be
+#           used if the currently-running release is not itself an LTS
+#           release, since in that case the upgrader won't be able to
+#           determine if a newer release is available.
