I'm not sure if this is intentional or not, but as of Fedora-Atomic-24-20160913.0 - this is the 'two week Atomic' nightly compose series - the Atomic installer DVD image seems to have the pre-release 'timbuktu' warning dialog, which it never had before: https://openqa.fedoraproject.org/tests/34121#step/_boot_to_anaconda/9 this causes the openQA test to fail. If it's meant to be there, I can adjust the test, if it's a bug...I guess fix it? :) Not sure who's at fault (if it's wrong), starting with pungi.
I filed this as https://pagure.io/releng/issue/108
This was indeed an issue in Pungi: https://pagure.io/pungi/issue/399 It should be fixed in version 4.1.9 that was released yesterday.
This looks to have been resolved, the last tested F24 Atomic image didn't have this issue (test failed due to a needle issue I should fix).
