Left over /image directory in images

[Vogtinator]

Problem description

I noticed that openSUSE MicroOS images have an empty /images directory in the root filesystem.

Expected behaviour

The empty directory should be deleted by kiwi.

Apparently this is handled by SystemSetup.cleanup, but it's not called anywhere.

Steps to reproduce the behaviour

https://build.opensuse.org/package/show/devel:microos:images/openSUSE-MicroOS is affected, but I guess any image with a disk.sh script triggers the same behaviour.

• Operating system host version: Tumbleweed
