This disables buffering for the standard output stream for python
executables spawn within the build root. This should help with
the ordering of text output in stages: when stdout is buffered,
debug messages via `print` will be end up in that buffer. When
executables are run in the stage, via `subprocess.run` their
stdout has its own buffering, which will be flushed at the end
of the run. If stdout was not manually flushed before invoking
the executable, the output of the tool will be emitted before
anything in the buffer. For example:
print("stage")
subprocess.run(["echo", "tool"])
Will lead have the following ordering:
"tool"
"stage"
To avoid this, without having to manually flush the stdout
buffer before every `subprocess.run`, disable buffering for
python binaries run inside the build root.

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 >= 3.7
Additionally, the built-in stages require:
bash >= 5.0coreutils >= 8.31curl >= 7.68qemu-img >= 4.2.0rpm >= 4.15tar >= 1.32util-linux >= 235
At build-time, the following software is required:
python-docutils >= 0.13pkg-config >= 0.29
Testing requires additional software:
pytest
Build
The standard python package system is used. Consult upstream documentation for detailed help. In most situations the following commands are sufficient to build and install from source:
python setup.py build
python setup.py install --skip-build --root=/
The man-pages require python-docutils and can be built via:
rst2man docs/<input-file>.rst <output-file>
