Even if one of the filters, either c.gh.debarshiray.toolbox or
c.rh.component, returns an empty list then the merged list of image
names would have an element that's an empty string. Some versions of
Podman (eg., 1.1.2) throw an error if an empty string is passed as the
image reference, while newer versions (eg., the snapshots leading to
1.2.0) will ignore the empty string and list all images. Therefore, in
the former case 'toolbox list' will error out; and in the latter case,
depending on whether only one of lists was empty or both, it will
either have duplicate entries or rightly return an empty output.

Toolbox — Unprivileged development environment
Toolbox is a tool that offers a familiar RPM based environment for developing and debugging software that runs fully unprivileged using Podman.
The toolbox container is a fully mutable container; when you see
yum install ansible
for example, that's something you can do inside your
toolbox container, without affecting the base operating system.
This is particularly useful on OSTree based Fedora systems like Silverblue. The intention of these systems is to discourage installation of software on the host, and instead install software as (or in) containers.
However, this tool doesn't require using an OSTree based system — it works equally well if you're running e.g. existing Fedora Workstation or 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 then
customized for the current user to create a toolbox container that seamlessly
integrates with the rest of the operating system.
Usage
Create your toolbox container:
[user@hostname ~]$ toolbox create
[user@hostname ~]$
This will create a container, and an image, called
fedora-toolbox-<your-username>:<version-id>
that's specifically customised
for your host user.
Enter the toolbox:
[user@hostname ~]$ toolbox enter
🔹[user@toolbox ~]$
