Manual Rollbacks

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.

Temporary rollback

To temporarily boot the previous OS deployment, hold down Shift during the OS boot process. When the bootloader menus appears, select the relevant OS entry in the menu.

Permanent rollback

To permanently revert to the previous OS deployment, log into the target node, and run rpm-ostree rollback -r. This operation marks the previous OS deployment as the default, and immediately reboots into it.
