Hi IBM mainframe enthusiasts! After some time of standby, Tumbleweed build for IBM Z is working and triggering tests: https://build.opensuse.org/project/show/openSUSE:Factory:zSystems A lot of packages still need love, but installer works. Tests are now adapted and passing: https://openqa.opensuse.org/group_overview/34 https://openqa.opensuse.org/tests/1171171 There is only one bug that needs to be worked around for the installation. See https://bugzilla.suse.com/show_bug.cgi?id=1156047 TLDR -> Add to linuxrc: "hardened_usercopy=off" We have ISO! http://download.opensuse.org/ports/zsystems/tumbleweed/iso/ We have repo! http://download.opensuse.org/ports/zsystems/tumbleweed/repo/oss/ Enjoy! Thanks Mike and Berthold for your help. Kind Regards, Sergio
