• FOSDEM talk by Sarah, recording and slides: https://fosdem.org/2022/schedule/event/collaboration_instead_of_competition/
  • Others are welcome to give talks! Just keep us all in the loop so the Open Mainframe Project can help support and promote the talks.
• Bugs across distributions:
  • https://bugzilla.opensuse.org/show_bug.cgi?id=1193889 from OpenSUSE bug tracker, but there’s one internally to IBM (for those who have access) https://bugzilla.linux.ibm.com/show_bug.cgi?id=196109
  • Debian installer issue with different glibc version than currently ships, related error
    • Jan 23 06:16:24 s390-zfcp[3825]: WARNING **: Could not open directory: /sys/bus/ccw/drivers/zfcp/: No such file or directory

    • Look into the public Debian build system? And folks handling that. Also folks working on D-I in general.
    • Lyz and Dipak will look into where in Debian they need to dig in more to get required builds for s390x updated.
  • LLVM compile issues with Postgres
    • https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1002029
    • https://github.com/llvm/llvm-project/issues/53009
    • Likely related from openSUSE (w/ RHEL patch): https://build.opensuse.org/package/view_file/openSUSE:Factory:zSystems/postgresql14/0001-jit-Workaround-potential-datalayout-mismatch-on-s390.patch?expand=1
  • New instructions are being added to QMU by some efforts driven by IBM, but there are some issues with KVM & LLVM (wasn't able to capture more details here, can someone else fill in?)

Sarah mentioned that openSUSE is working on an installer issue with packages getting installed, but after the restart it to finish the installer (bootloader, etc) there is a problem.

David mentioned a systemd crash problem on Fedora Rawhide (https://bugzilla.redhat.com/show_bug.cgi?id=1986176) - maybe related to the openSUSE problem? Sarah will look into their systemd situation.
