This directory will contain expected files in the base image.
That said, I may change the container import path to auto-create
at least the sysroot dir and symlink at some point and these
can just be dropped.
And for that matter after
9a0acd7249
"libostree/deploy: enable composefs by default"
we can likely just drop the prepare-root bit too.
But for now this is needed.

bootc
Transactional, in-place operating system updates using OCI/Docker container images.
Motivation
The original Docker container model of using "layers" to model applications has been extremely successful. This project aims to apply the same technique for bootable host systems - using standard OCI/Docker containers as a transport and delivery format for base operating system updates.
The container image includes a Linux kernel (in e.g. /usr/lib/modules),
which is used to boot. At runtime on a target system, the base userspace is
not itself running in a "container" by default. For example, assuming
systemd is in use, systemd acts as pid1 as usual - there's no "outer" process.
More about this in the docs; see below.
Status
The CLI and API are considered stable. We will ensure that every existing system can be upgraded in place seamlessly across any future changes.
Documentation
See the project documentation.
Adopters (base and end-user images)
The bootc CLI is just a client system; it is not tied to any particular operating system or Linux distribution. You very likely want to actually start by looking at ADOPTERS.md.
Community discussion
The Github discussion forum is enabled.
This project is also tightly related to the previously mentioned Fedora/CentOS bootc project, and many developers monitor the relevant discussion forums there. In particular there's a Matrix channel and a weekly video call meeting for example: https://docs.fedoraproject.org/en-US/bootc/community/.
