@kedvall You can check my post here about OpenSUSE Leap Micro 6.1 network boot installation. In the my_network_boot/get_files.sh file in that post you will find the link to the download CDN and you will get files with RT in the name like openSUSE-Leap-Micro.x86_64-6.1-Base-RT-SelfInstall-Build5.7.install.tar that sounds like a real time installation image - at least that’s what I thought when I saw the name.
