This stage allows you to create new (random) ed25519 keys as used by `ostree sign`. The primary usecase for this is composefs. You can generate a transient key-pair during the build (unique to the build) that binds the initrd to the userspace tree. You put the public key in the initrd, sign the resulting commit with the private key and then throw away the private key. During boot of a (secureboot trusted) initrd, we use this public key to validate that we're booting the right commit. This is similar to how the transient kernel module signatures work. It similarly generates a keypair during the kernel rpm build, sign the modules, throw away the private key and embed the public key in the kernel binary. Of course, this stage can also be used to generate keys used for persistant signatures. |

OSBuild
Build-Pipelines for Operating System Artifacts
OSBuild is a pipeline-based build system for operating system artifacts. It defines a universal pipeline description and a build system to execute them, producing artifacts like operating system images, working towards an image build pipeline that is more comprehensible, reproducible, and extendable.
See the osbuild(1) man-page for details on how to run osbuild, the definition
of the pipeline description, and more.

Requirements
The requirements for this project are:
bubblewrap >= 0.4.0python >= 3.6
Additionally, the built-in stages require:
bash >= 5.0coreutils >= 8.31curl >= 7.68qemu-img >= 4.2.0rpm >= 4.15tar >= 1.32util-linux >= 235skopeo
At build-time, the following software is required:
python-docutils >= 0.13pkg-config >= 0.29
Testing requires additional software:
pytest
Installation
Installing osbuild requires to not only install the osbuild module, but also
additional artifacts such as tools (i.e: osbuild-mpp) sources, stages, schemas
and SELinux policies.
For this reason, doing an installation from source is not trivial and the easier way to install it is to create the set of RPMs that contain all these components.
This can be done with the rpm make target, i.e:
make rpm
A set of RPMs will be created in the ./rpmbuild/RPMS/noarch/ directory and can
be installed in the system using the distribution package manager, i.e:
sudo dnf install ./rpmbuild/RPMS/noarch/*.rpm
