From 1abb2174934a461d90885afc0a8655e9d326f21e Mon Sep 17 00:00:00 2001 From: Chris Evich Date: Wed, 10 Jul 2019 12:15:43 -0400 Subject: Cirrus: Disable most periodic services/timers For CI testing, it's important to remove as much variability from the overall system as possible. This permits focusing just on problems closely related to code-changes. To this end, and because VMs are very short-lived (2 hours at most), disable all systemd services and timers which perform periodic activities.
