A subsequent commit will generate the name of the toolbox container
from that of the user-specific customize image, instead of just using
the same exact string. This is necessary because, unlike OCI images,
names of OCI containers can't have a colon in them [1]. Knowing that
the user-specific customized image always has a tag will make things
simpler.
Buildah and Podman are going to use 'latest' as the placeholder when no
tag is specified, and this what is explicitly mentioned when the base
toolbox image is referred to by its non-human-readable ID.

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 ~]$
