+Subject: [PATCH] meson: add systemd option
+
+We may not always want to link against systemd even if installed - consider
+the case where a user is switching from systemd->another init system, systemd
+may still be installed temporarily but the user wants to rebuild without it.
+
+This perserves the default behaviour of using systemd if available.
