Synopsis
Description
Deploy and transactionally in-place with bootable container images.
The `bootc` project currently uses ostree-containers as a backend to support a model of bootable container images. Once installed, whether directly via `bootc install` (executed as part of a container) or via another mechanism such as an OS installer tool, further updates can be pulled and `bootc upgrade`.
Options
