Dear Madam or Sir,


Linux logs several warnings on the Dell Precision 3540.

```

[  113.577465] systemd[1]: /lib/systemd/system/rstudio-server.service:11: Unit uses KillMode=none. This is unsafe, as it disables systemd's process lifecycle management for the service.

```

The accelerator warning could be quickly solved with the help of the Linux kernel community [1].

Could Canonical/Ubuntu please make it a requirement for certification, that `dmesg --level=crit,alert,err,warn` is empty.


Kind regards,

Paul
