This is the full definition of the UBI-based toolbox image published for
RHEL 9.1 [1] at registry.access.redhat.com/ubi9/toolbox:9.1. Note that
the Dockerfile used to build this image was already available to the
public [2], but didn't include all the files necessary to build it.
However, this has some minor deviations from the published image. The
FROM line has been changed to registry.access.redhat.com/ubi9:9.1 so
that it can be built outside Red Hat's build system and always points to
the desired RHEL version. The extra-packages file doesn't have
gnupg2-smime because it doesn't seem to be actually part of the UBI RPM
repositories, and it's not clear how it works inside Red Hat's build
system. Otherwise, 'podman build' fails with:
STEP 11/14: RUN dnf -y install $(<extra-packages)
