When you do this, `bootc upgrade` will always be a no-op. In this model, upgrades are then always triggered by further `switch` operations. + ## Applying Changes The `--apply` option will automatically take action (rebooting) if the system has changed after switching to the new image. Currently, this option always reboots the system. In the future, this command may detect cases where no kernel changes are queued and perform a userspace-only restart instead.
