Default community distributions are running in the same issues for special architectures. Every Linux distribution has got mostly separate maintainers and hardware distributors are handling these communities really often disconnected. That has been identified also for the architecture s390x. Therefore, openSUSE, Fedora and Debian have established together with IBM a Linux Distributions Working Group for a better collaboration together and with the goal to receive better support. In this presentation you should receive an overview about a good collaboration between Linux distributions and what you can achieve together with such a Working Group.
