installer session broken and cannot limit the luns display

[bugproxy]

Having loaded the boot loader and entered the ssh connection via installer. During the FCP disk discovery, it shows all luns can be seen. I think it's supposed to display only the lun I specified in the kernel parameter. And when I move the cursors up and down, the ssh connection will break. It happens very often.

This is not how the preseeds work with d-i on Debian/Ubuntu.

Specifying s390-zfcp/zfcp like that preseeds the answers for that question, however the question may still be shown.
The questions shown depend on the priority of the installer (default is high) and thus this question will still be asked.

If you are trying to achieve fully automated installation, you would need to raise the priority of the installer to critical only; but also preseed answers for many other questions too.

If you can still reproduce the problem, please extract and attach installer logs /var/log/syslog from the running / crashed installer.
