+        When systemd-hostnamed is used it is strongly recommended to
+        install nss-myhostname to ensure that in a world of
+        dynamically changing hostnames the hostname stays resolvable
+        under all circumstances. In fact, systemd-hostnamed will warn
+        if nss-myhostname is not installed. Packagers are encouraged to
+        add a dependency on nss-myhostname to the package that
+        includes systemd-hostnamed.
+
+        Note that D-Bus can link against libsystemd-login.so, which
+        results in a cyclic build dependency. To accommodate for this
+        please build D-Bus without systemd first, then build systemd,
+        then rebuild D-Bus with systemd support.
