+Subject: [PATCH] init: Only print shutdown messages to log
+
+We disable them from appearing on the console so users are not confused
+as the system kexec's to the next kernel. This suppresses these
+messages:
+
+ The system is going down NOW!
+ Sent SIGTERM to all processes
+ Sent SIGKILL to all processes
