I already discussed this with Martin Schwidefsky and we decided *not* to go via stable but instead "warn" Ubuntu explicitly.

AFAIK you are the only official distribution that uses 4.13 for zfcpdump - therefore IMHO this should be sufficient.

I did not check anything - this bugzilla was just a heads-up.
