distro-agnotic is certainly important.
I would have gone with:

diff --git a/utils/statd/start-statd b/utils/statd/start-statd
index dcdaf7763f18..414f73f58096 100644
--- a/utils/statd/start-statd
+++ b/utils/statd/start-statd
@@ -5,7 +5,7 @@
 # It should run statd with whatever flags are apropriate for this
 # site.
 PATH="/sbin:/usr/sbin:/bin:/usr/bin"
-if systemctl start rpc-statd.service
+if systemctl start rpc-statd.service > /dev/null 2>&1
 then :
 else
     exec rpc.statd --no-notify


why call systemctl twice (once with --help and once with "start")?
