## Observation

openQA test in scenario opensuse-Tumbleweed-DVD-x86_64-gnuhealth@64bit fails in
[gnuhealth_install](https://openqa.opensuse.org/tests/775786/modules/gnuhealth_install/steps/5)
on the command `whoami > /dev/ttyS0` as root .

in https://openqa.opensuse.org/tests/775786/file/gnuhealth_install-journal.log
it says

```
Oct 17 02:12:09 susetest agetty[1849]: /dev/ttyS0: not a tty
```

and then later

```
Oct 17 02:12:19 susetest systemd[1]: serial-getty@ttyS0.service: Service
RestartSec=100ms expired, scheduling restart.
Oct 17 02:12:19 susetest systemd[1]: serial-getty@ttyS0.service: Scheduled
restart job, restart counter is at 1.
Oct 17 02:12:19 susetest Stopped Serial Getty on ttyS0.
Oct 17 02:12:19 susetest systemd[1]: Started Serial Getty on ttyS0.
```

so a lot of stuff going on regarding ttyS0 and also it is not exactly new:
https://openqa.opensuse.org/tests/763584#step/gnuhealth_install/5 from 18 days
ago


## Reproducible

Fails since (at least) Build
[20181015](https://openqa.opensuse.org/tests/775239)


## Expected result

Last good: [20180815](https://openqa.opensuse.org/tests/734371/)
we can consider ourselves lucky that there was a bug a bit later in the test 2
months ago because we have the journal file showing that there is no problem
(or I could not find one):
https://openqa.opensuse.org/tests/734371/file/gnuhealth_install-journal.log ,
there is just

```
Aug 16 18:26:39 susetest systemd[1]: Started Serial Getty on ttyS0.
```

no further message.
