Ubuntu supports NVMe Multipath on all architectures in Focal. I know that some other distributions do not.

Setting nvme-core.multipath=0 for s390x isos only, or changing kernel config to disable multipath to "n" on s390x only, would mean regression on s390x as compared with amd64/arm64/ppc64le.

That would be suboptimal.

Do you have no plans to support multipath NVMe and are customers who buy expensive multipath capable NVMe drives will not be able to use multipath capability with them? Or for example is multipath handled separately on Z with NVMe? (ie. HMC mediated)

My preference would be to see a chreipl fix upstream in s390-tools to add support for multipath nvme drives, and SRU that too.
