do we know which s390x machines ELN builds on?
The koji builders are Z13. They are running a Fedora kernel to do the build,
so the 5.13-rc5 eln build was done in koji running 5.12.8-300.fc34. These
tend to be updated regularly with Fedora, but we do not plan to set to Z14 in
Fedora. Of course the build root is running eln userspace packages, so we
would need to ensure that nothing in userspace requires Z14, or it will fail.
I don't recall Z14 adding a bunch of new instructions, so this might not be an
issue.
