+  * [d24b1734] Support overrides in tmpfiles.d (LP: #1748147)
+    - dh_installsystemd: Use the basename of the "tmpfiles" config
+      files.  This makes "systemd-tmpfiles --create" search for it
+      in both /usr/lib/tmpfiles.d and in /etc/tmpfiles.d. With
+      this change the system administrator can now override the
+      "tmpfiles" config shipped by the package in
+      /usr/libtmpfiles.d.
+    - dh_installinit: Ditto.
