Broadcast message from locksmithd at 2021-06-30 01:12:57.435199363 +0000 UTC m
System reboot in 5 minutes!

To disable auto update:
If you wish to disable automatic updates permanently, use can configure this with a Container Linux Config. This example will stop update-engine, which executes the updates, and locksmithd, which coordinates reboots across the cluster:

systemd:
  units:
    - name: update-engine.service
      mask: true
    - name: locksmithd.service
      mask: true

Need to disable the auto reboot strategy.
