bootc-rollback - Man Page

bootc rollback [--apply] [-h|--help]

Change the bootloader entry ordering; the deployment under `rollback` will be queued for the next boot, and the current will become rollback.  If there is a `staged` entry (an unapplied, queued upgrade) then it will be discarded.

Note that absent any additional control logic, if there is an active agent doing automated upgrades (such as the default `bootc-fetch-apply-updates.timer` and associated `.service`) the change here may be reverted.  It's recommended to only use this in concert with an agent that is in active control.

A systemd journal message will be logged with `MESSAGE_ID=26f3b1eb24464d12aa5e7b544a6b5468` in order to detect a rollback invocation.

--apply

Restart or reboot into the rollback image.

Currently, this option always reboots.  In the future this command will detect the case where no kernel changes are queued, and perform a userspace-only restart.

-h,  --help

Print help (see a summary with '-h')

Note on Rollbacks and the `/etc` Directory:

When you perform a rollback (e.g., with `bootc rollback`), any changes made to files in the `/etc` directory won’t carry over to the rolled-back deployment.  The `/etc` files will revert to their state from that previous deployment instead.

This is because `bootc rollback` just reorders the existing deployments. It doesn't create new deployments. The `/etc` merges happen when new deployments are created.
