Comment 4 for bug 2019089

@paelzer Thanks

> I see this only goes back to Jammy

Yes this affects jammy+ only but the patch would likely go back to previous releases too as part of the SRU exception and future bug and feature releases.

I have verified your proposed change too and the resulting `preinst` remains the same

```
dh_installsystemd --no-start --no-stop-on-upgrade google-startup-scripts.service google-shutdown-scripts.service
```

I see from man pages [bionic](https://manpages.ubuntu.com/manpages/bionic/en/man1/dh_installsystemd.1.html),[focal]( https://manpages.ubuntu.com/manpages/focal/en/man1/dh_installsystemd.1.html), [jammy](https://manpages.ubuntu.com/manpages/jammy/en/man1/dh_installsystemd.1.html), [kinetic+](https://manpages.ubuntu.com/manpages/kinetic/en/man1/dh_installsystemd.1.html) that --no-stop-on-upgrade` is available so, as you say, likely no issues with backporting.
