Tom Gundersen e97f6ef34e objectstore: don't store objects by their treesum 
The treesum of a filesystem tree is the content hash of all its
files, its directory structure and file metadata.

By storing trees by their treesum we avoid storing duplicates of
identical trees, at the cost of computing the hashes for every
commit to the store.

This has limited benefit as the likelihood of two trees being
identical is slim, in particular when we already have the ability
to cache based on pipeline/stage ID (i.e., we can avoid rebuilding
trees if the pipelines that built them were the same).

Drop the concept of a treesum entirely, even though I very much
liked the idea in theory...

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.

Please refer to the developer guide to learn about our workflow, code style and more.

Requirements

The requirements for this project are:

  • bubblewrap >= 0.4.0
  • python >= 3.7

Additionally, the built-in stages require:

  • bash >= 5.0
  • coreutils >= 8.31
  • curl >= 7.68
  • qemu-img >= 4.2.0
  • rpm >= 4.15
  • tar >= 1.32
  • util-linux >= 235

At build-time, the following software is required:

  • python-docutils >= 0.13
  • pkg-config >= 0.29

Testing requires additional software:

  • pytest

Install

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
