Currently, if 'skopeo copy ...' fails to download and cache an OCI image
during setup_suite(), the test suite doesn't immediately fail, but
continues. It only fails later when trying to set up the Docker
registry and contains a lot of noise:

It makes it look as if the root cause of the failure is related to
setting up the Docker registry, which it isn't, and all that noise makes
it difficult to spot the actual problem.
Instead, from now on, it will be more obvious:
not ok 1 setup_suite
# (from function `setup_suite' in test file
test/system/setup_suite.bash, line 44)
# `_pull_and_cache_distro_image "$system_id" "$system_version" ||

source docker://registry.fedoraproject.org/fedora-toolbox:38-foo:
reading manifest 38-foo in
registry.fedoraproject.org/fedora-toolbox: manifest unknown"
Note that Bats' 'run' helper [1] isn't designed to work inside
setup_suite(). eg., 'run --separate-stderr' doesn't work because
BATS_TEST_TMPDIR isn't defined.

Toolbox is a tool for Linux, which allows the use of interactive command line environments for development and troubleshooting the host operating system, without having to install software on the host. It is built on top of Podman and other standard container technologies from OCI.
Toolbox environments have seamless access to the user's home directory, the Wayland and X11 sockets, networking (including Avahi), removable devices (like USB sticks), systemd journal, SSH agent, D-Bus, ulimits, /dev and the udev database, etc..
This is particularly useful on OSTree based operating systems like Fedora CoreOS and Silverblue. The intention of these systems is to discourage installation of software on the host, and instead install software as (or in) containers — they mostly don't even have package managers like DNF or YUM. This makes it difficult to set up a development environment or troubleshoot the operating system in the usual way.
Toolbox solves this problem by providing a fully mutable container within
which one can install their favourite development and troubleshooting tools,
editors and SDKs. For example, it's possible to do yum install ansible
without affecting the base operating system.
However, this tool doesn't require using an OSTree based system. It works equally well on Fedora Workstation and Server, and that's a useful way to incrementally adopt containerization.
The toolbox environment is based on an OCI
image. On Fedora this is the fedora-toolbox image. This image is used to
create a toolbox container that offers the interactive command line
environment.
Note that Toolbox makes no promise about security beyond what's already available in the usual command line environment on the host that everybody is familiar with.
