+- Require /usr/bin/dbus-daemon by the devel package: GDBusTest
+  launches an own dbus-daemon with a separate environment, so that
+  test code does not have to rely on the session bus. Ensure
+  consumers of GDBusTest have the needed dep present.
+- Change the dbus-launch Requires to %{_bindir}/dbus-launch: be
+  flexible about potential future package layout changes.
