# At a later point, re-enable it to re-align with the tip of stream
sudo systemctl enable --now zincati.service
# Disable Zincati in order to opt-out from future auto-updates
sudo systemctl disable --now zincati.service
If you prefer, you can temporarily turn off auto-updates. Later on, you can re-enable them in order to let the machine catch up with the usual flow of updates:
Manual Rollbacks
# Mark the previous OS deployment as the default, and immediately reboots into it
sudo rpm-ostree rollback -r
Permanent rollback
Please note that Zincati will keep looking for updates and upgrade to any new available OS deployment, other than the one you just reverted.
# Stop the service that performs automatic updates
sudo systemctl stop zincati.service
Temporary rollback
To permanently revert to the previous OS deployment, log into the target node and run the following commands:
To temporarily boot the previous OS deployment, hold down `Shift` during the OS boot process. When the bootloader menu appears, select the relevant OS entry in the menu.
When an update is complete, the previous OS deployment remains on disk. If an update causes issues, you can use it as a fallback. This is a manual operation that requires human intervention and console access.
