+  * journald: Backport support for --relinquish and --smart-relinquish options.
+    Newer version of systemd-journald support the --relinquish and
+    --smart-relinquish options that enable cleaner handling of mounts at
+    shutdown as journald can be told to close any logging under
+    /var/log/journal so that the /var filesystem can be unmounted should it be
+    on a separate partition.
+    Backport this feature as it enables shutdown without failures, a highly
+    desirable trait in embedded products using systemd.
