Description

In https://openqa.opensuse.org/tests/4826592#step/_root_BCI-tests_minimal_/1 we discovered that the image size of the BCI/Minimal container for Tumbleweed grew unexpectedly. See https://bugzilla.opensuse.org/show_bug.cgi?id=1236736.

We have been tasked to investigate what exactly grew.

We can use the latest published BCI containers (you'll find them in https://registry.opensuse.org/cgi-bin/cooverview) and compare those with the container images that are pending: registry.opensuse.org/opensuse/factory/totest/containers/opensuse/bci/bci-minimal:latest.

Then compare the two images and investigate what makes the huge difference.

Report back here.
