ZSystems

Welcome to the ZSystems edit

openSUSE for IBM Z and LinuxONE is on its way!

Due to the demand for an open z Systems distribution, we started to build the architecture s390x on the Open Build Service. Find the development project page at openSUSE:Factory:zSystems. If you want to contribute, it is recommended to submit patches via openSUSE:Factory. They will be transferred to the zSystems port after the approval.

Please join the opensuse-zsystems mailing list for questions or help.

Topics edit

openSUSE Tumbleweed

The first installable testversion of openSUSE Tumbleweed is available. To install, use the repositories available at http://download.opensuse.org/ports/zsystems/tumbleweed/repo/oss/ or download the ISO image from http://download.opensuse.org/ports/zsystems/tumbleweed/iso/. Note, that this project is a port to Tumbleweed, and not a fully supported architecture.

For more information about Tumbleweed, see Tumbleweed.

Testing

Automatic tests are performed by openQA and are publicly available: https://openqa.opensuse.org/group_overview/34

The more adventerous people might want to check out the untested images. The latest image is always found at:

• https://build.opensuse.org/package/binaries/openSUSE:Factory:zSystems/000product:openSUSE-dvd5-dvd-s390x/images

You can report bugs for Tumbleweed and Leap in our openSUSE Bugzilla.

Participate

• Find the current status of the project at the starting page at openSUSE:Factory:zSystems.
• Tutorial how get get involved can be found at openSUSE:Build_Service_Tutorial.
• To run manual builds, get yourself a community cloud access from IBM at LinuxONE Community Cloud. Find a short intro how to get into there at ZSystems/Community cloud access. Upgrade SLES to openSUSE.
• openSUSE:Factory:zSystems is based on openSUSE:Factory. All submissions should thus go to openSUSE:Factory or the respective development projects.

Things to do edit

• Fix ZSystems/Failing_Packages (including becoming a watcher of the openSUSE:Factory:zSystems poject (add it to your watch list from within the OpenSUSE build service webUI)
• Create Container Images for s390x
• Good First Issues
• Get awareness of openSUSE community
• Find partners that help with building openSUSE

Trainings/Meetings edit

We provide bi-weekly meetings with trainings for knowledge sharing in our team. That includes mainframe topics, packaging, OBS and containerization.

• bi-weekly Tuesday: 18:00 (German time)/ 9:00 (Pacific time)/ 17:00 (Nigeria) / 13:00 (Brazil)
