+# This is copied from systemd-sysupdate.timer; it's just an arbitrary
+# starting point.
+#
+# Trigger the update 1 hour after boot, and then – on average – every 6h, but
+# randomly distributed in a 2h…6h interval. In addition trigger things
+# persistently once on each Saturday, to ensure that even on systems that are
+# never booted up for long we have a chance to do the update.

-OnUnitInactiveSec=8h
-# When deploying a large number of systems, it may be beneficial to increase this value to help with load on the registry.
