No text/status output anymore in final 'installing system' screen

[Frank Heimes]

Using the daily image:
jammy-live-server-s390x.iso 2022-01-27
I've noticed that the final subiquity screen, that usually shows the status of the installation and what is currently done, stays empty.

However, that only impacts the installer output in the middle, the framework/decoration is still there, even the help menu overlay is displayed properly.
But selecting 'View full log' also does not show anything.

The installation itself completed and the button on the bottom eventually switched to "reboot now" and the reboot completes and I can login to the system.

Hence it seems to be a display issue only.

I tried two installation (LPAR and z/VM) and happens in both cases - it's inside the remote ssh session anyway.
(I may try the integrated ASCII console while doing an LPAR installation on top ...)

We probably want to set SYSTEMD_JOURNAL_KEYED_HASH=0 in a systemd-journald.service.d/override.conf in the installer context, so that the generated journal files are still compatible with older versions of systemd.

I think we need to disable compression too (systemd in jammy defaults to zstd). I thought I fixed this though... maybe I dropped the ball somewhere :/
