For a locally built squashed fedora-toolbox:29 image [1], the size
reported by 'podman images' goes from 630 MB to 425 MB.

There's no easy way to introspect the Kerberos configuration from the
command line. eg., the credential cache type being used, or the value
of the socket_path setting that denotes which socket the KCM service
will listen on. Therefore, it's assumed that the former is KCM if the
socket's path can be parsed from the sssd-kcm.socket unit.
Given the immutable nature of Podman containers, the toolbox container
and its corresponding image will have to be re-created if the host OS
is sufficiently re-configured.
The krb5-libs package was added to the base toolbox images to ensure
the presence of the /etc/krb5.conf.d directory with the correct
permissions. Currently, the package is already pulled in by various
dependencies. Therefore, it doesn't increase the size of the base
image, but serves as a safeguard against any inadvertent changes.

This is necessary for the toolbox script to work inside the toolbox
container [1]. Having the flatpak-spawn command, provided by the
flatpak-xdg-utils package, readily available in the base image makes
for a better out of the box experience.
The flatpak-xdg-utils package is not available on Fedora 28. Given
that Fedora 28 is getting close to the end of its life cycle, it's
probably not worth doing all the paperwork to offer the package there.

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.
