Thanks Peter, but one reason for the new sftp-server cluster HA architecture (and therefore the central NFS mount for the users, leading to this problem)
was to be able to have maintenance of the single sftp servers without service outage, to be able to apply operating system security patches delivered by the distribution (Ubuntu in this case).
I have no capacity to follow the OpenSSH security issues myself an then if needed re-compile newer patched versions (and not even then apply your patch additionally every time to it :)
We do here industry production service and need to stick with vanilla distribution OpenSSH and leave the delivery security patches to Ubuntu.

Thanks for the hint, I will look into it, I am not so experienced with systemd yet.
