+Subject: [PATCH] #5921: Use libsystemd instead of libsystemd-daemon (original
+ patches by Sandro Tosi and Mike Gilbert)
+
+In systemd v209, released over two years ago, the various libsystemd-*
+libraries (libsystemd-journal.so, libsystemd-login.so, libsystem-daemon.so,
+libsystemd-id128.so) were merged into a single libsystemd.so library to
+reduce code duplication and avoid cyclic dependencies.
+
