This is the main utility responsible for prefetching packages
into local `base-apt` repo from external Debian mirrors. It uses
python-apt module and requires some kind of minimal `rootfs` to work
(let's call it "debrepo context").

Once initialized with `--init --workdir=3D<path>`, it stores the init=
ial
configuration in `repo.opts` file inside the context and uses it at
futher calls.

In future, the logic `debrepo` script implements could be directly
implemented inside bitbake classes.

Searching for subprocess.run() delivers wget and reprepro as external
dependencies. As I can't see any exception handling: What happens if
those dependencies are not installed / available in the calling context?

Florian

In this case the child_exception_type is raised in subprocess.py.
