The daemon branch landing upstream meant the %files section broke.
Let's switch to something more relaxed.

+# I try to do continuous delivery via rpmdistro-gitoverlay while

+# mandatory file entries.  What this is doing is making each file
+# entry optional - if it exists it will be picked up.  That
+# way the same spec file works more easily across multiple versions where e.g. an
+# older version might not have a systemd unit file.
