The "fedora" prefix was used because this project was specifically incubated to make it easier to hack on Fedora Silverblue. That and the mix of upstream technologies (ie., Buildah and Podman) made it uniquely "Fedora". However, over time it has gotten clear that other groups, currently Fedora downstreams like RHEL, are interested in it too. It won't be surprising if in future it transcends the Fedora universe altogether. Moreover, this project was inspired by coreos/toolbox [1]. There are good reasons and enough interest to have a unified toolbox project that addresses the needs of both Fedora CoreOS and Silverblue. Therefore, it is best to drop the "fedora" prefix and call the whole thing just "toolbox". No extra effort was made to retain compatibility with the older name due to the project's young age. Its userbase is limited to the earliest of early adopters, and the benefits of a clean break outweigh the loss of compatibility. The OCI images and the toolbox container still retain the "fedora" prefix to disambiguate them from their counterparts from other operating systems.

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 project 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 ~]$
