bootc command [options]

bootc manages transactional, in-place operating system updates using OCI/Docker container images. It enables atomic system upgrades where the entire OS is replaced by a new container image at boot time.
The tool works with image-based Linux distributions like Fedora CoreOS and provides rollback capability if updates cause issues.

--check

Check for updates without applying them

Apply upgrade and reboot

status

Show current deployments and their order in bootloader

Fetch and stage a new version of the OS

Change to a different container image

Revert to the previous OS deployment

Apply configuration changes transactionally

Only works on systems designed for bootc (image-based Linux distributions). Changes to root filesystem are lost unless using configuration management. Requires container image infrastructure.

bootc is part of the growing ecosystem of image-based Linux systems, building on technologies like OSTree and container images. It represents a modern approach to system updates pioneered by projects like CoreOS.
