+# Monitor all units, slices, etc. for OOM conditions based on current swap usage
+# (default limit is 90% swap use).  When the system uses more swap than this
+# limit system will start acting on control groups using most swap, in order
+# of swap usage (see oomd.conf(5) for details).
+#
+# systemd recommends to set this on the root slice (see systemd-oomd.service(8)).

+# systemd does not recommend to generally act upon memory pressure, because most
+# system services run fine under memory pressure, and latency (i.e. having a
+# responsive service) is usually not important for system services (which are
+# mostly invisible anyway).
