From 6f5d79986a9c98b9cacc83f865fed957e4e6e4e6 Mon Sep 17 00:00:00 2001 From: Zbigniew Jędrzejewski-Szmek Date: Thu, 26 Nov 2015 16:32:41 -0500 Subject: core: rename Random* to RandomizedDelay* The name RandomSec is too generic: "Sec" just specifies the default unit type, and "Random" by itself is not enough. Rename to something that should give the user general idea what the setting does without looking at documentation. --- man/systemd.timer.xml | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'man') diff --git a/man/systemd.timer.xml b/man/systemd.timer.xml index fd03bda9cd..dcd7b90ee5 100644 --- a/man/systemd.timer.xml +++ b/man/systemd.timer.xml @@ -205,7 +205,7 @@ - RandomSec= + RandomizedDelaySec= Delay the timer by a randomly selected, evenly distributed amount of time between 0 and the specified time @@ -222,16 +222,16 @@ time range in order to minimize wakeups, the former does the opposite: it stretches timer events over a time range, to make it unlikely that they fire simultaneously.

In order to optimally stretch timer events over a certain range of time, make sure to set - RandomSec= to a higher value, and + RandomizedDelaySec= to a higher value, and AccuracySec=1us. -- cgit v1.2.3-54-g00ecf
