gnome-initial-setup doesn't want to create new user in custom LiveCD
I made custom Fedora 28 Workstation LiveCD but struggle with bug after first boot into newly installed system. New user is not created and gnome-initial-setup
appears again every time after re-login/reboot. What can cause this? How to debug this?
