Fedora Toolbox is a tool that offers a familiar RPM based environment for developing and debugging software on locked down OSTree based Fedora systems like Silverblue. Such operating systems are shipped as immutable OSTree images, where it's difficult to setup a development environment with your favorite tools, editors and SDKs. A toolbox container solves that problem by providing a RPM based mutable container. You can tweak it to your heart's content and use DNF to install your favorite packages, all without worrying about breaking your operating system.
The toolbox environment is based on 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.
[user@hostname fedora-toolbox]$ ./fedora-toolbox create
[user@hostname fedora-toolbox]$
This will create a container, and an image, called
fedora-toolbox-<your-username>:<version-id> that's specifically customised
for your host user.
[user@hostname fedora-toolbox]$ ./fedora-toolbox enter
🔹[user@toolbox ~]$
