Shortly after the update has been staged the system will reboot by default. However if it detects active user sessions it will wait and show a message to the user:
Broadcast message from Zincati at Thu 2023-08-03 19:52:55 UTC:
New update 38.20230709.3.0 is available and has been deployed.
If permitted by the update strategy, Zincati will reboot into this update when
all interactive users have logged out, or in 10 minutes, whichever comes
earlier. Please log out of all active sessions in order to let the auto-update
process continue.
Once the user sessions have ceased the reboot will continue. In this case we need to stop the autologin on ttyS0 service and log out of SSH as well:
[core@localhost ~]$ sudo systemctl stop serial-getty@ttyS0.service
[core@localhost ~]$ exit
logout
Connection to 192.168.124.222 closed.
You can monitor the serial console to see when the machine has performed the reboot via `virsh console fcos`.
When we log back in we can view the current version of Fedora CoreOS is now the latest one. The `rpm-ostree status` output will also show the older version, which still exists in case we need to rollback:
[core@localhost ~]$ rpm-ostree status
State: idle
AutomaticUpdatesDriver: Zincati
DriverState: active; periodically polling for updates (last checked Thu 2023-08-03 19:59:16 UTC)

The currently booted deployment is denoted by the `●` character.
You can view the differences between the two versions by running an `rpm-ostree db diff` command:
[core@localhost ~]$ rpm-ostree db diff

Reverting to the previous version
If the system is not functioning fully for whatever reason we can go back to the previous version:
sudo rpm-ostree rollback --reboot
After logging back in after reboot we can see we are now booted back into the old deployment from before the upgrade occurred:
[core@localhost ~]$ rpm-ostree status

Cleanup
Now let's clean up the instance. Disconnect from the machine and then destroy it:
virsh destroy fcos
virsh undefine --remove-all-storage fcos
