+Again this won't work.
+eg: nginx provides a systemd unit but doesn't require systemd.
+So you cannot guaranty that systemd (& thus rpm-helper) will got
+installed prior those packages
+
+It's the all the packages that provides systemd units that should
+requires a recent enough rpm-helper.
+Not just systemd.
+
+> But what will happend to initscript/sysvinit installs ?
+
+Those will upgrade to systemd due to automatic
+choice between systemd & sysvinit-legacy.
