Hello Team, We want to build our CODE12 based products ("_product" package) on CODE15. I have been following the way openSUSE Leap 15.x and SLE15 products are being built, but I am not sure which "00X..." packages should contain which files. The Product Definition wiki page still refers to "_product" details: https://en.opensuse.org/openSUSE:Build_Service_Concept_Product_Definition I couldn't find any documentation in either the OBS User or Administrator guide. I also searched the KIWI-ng documentation. I found 2 mentions of building products, but I can't find any useful content: https://openbuildservice.org/2017/09/22/two-new-guides-for-builders/ https://github.com/openSUSE/obs-docu/blob/master/xml/obs_product_building.xm... I installed and ran the "obs-service-product_converter" service script locally on our existing "_product" package. After making a few changes to the My.product file, I was able to run the script. It generated following files: * A _multibuild file. * KIWI files for each media. * Keywords (KWD) files for each media. * Release package spec and changes files. My questions: * Where shall I place these files? In a package called 000product? * How do we use 000package-groups, 000release-packages, and 000update-repos * How were these packages created for the first time in openSUSE:Leap:15.1 project?
