-A sysctl handle under /proc/sys/net, which is managed by systemd-networkd, has been changed by another process.
-The event is raised only if the written value differs from the current one.
-The program name, the written value, the previous value, and the value initially set by networkd have been logged.
+The sysctl configuration setting @SYSCTL@, which is managed by
+systemd-networkd, has been changed by another, unrelated process
+("@OBJECT_COMM@", PID @OBJECT_PID@). This represents a conflict of ownership
+and will likely result in problems later on.
+
+Value changed to "@NEWVALUE@", which should be "@OURVALUE@".
