From c8e9877d14c8742cc3732d305af2422f8a16f47d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Wed, 17 Oct 2018 17:27:20 +0200 Subject: [PATCH] core: do not "warn" about mundane emergency actions For example in a container we'd log: Oct 17 17:01:10 rawhide systemd[1]: Started Power-Off. Oct 17 17:01:10 rawhide systemd[1]: Forcibly powering off: unit succeeded Oct 17 17:01:10 rawhide systemd[1]: Reached target Power-Off. Oct 17 17:01:10 rawhide systemd[1]: Shutting down. and on the console we'd write (in red) [ !! ] Forcibly powering off: unit succeeded This is not useful in any way, and the fact that we're calling an "emergency action" is an internal implementation detail. Let's log about c-a-d and the watchdog actions only.
