Timothée Ravier 77bb135f27 Use ARG instead of ENV to avoid leaking variables 
We only need those temporary variables for the container build and for
the LABELS. We do not want to set those specific environment variables
for the container environment itself.

Using ARG instead of ENV lets us do that.

README.md

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.
