applied, thanks!

But I made some follow-ups:

- fix typo and factor common message into single variable

- pass the suppress_stderr param from get_systemd_unit_state to avoid an ugly message
  for unaffected systems, i.e. like:
  "Failed to get unit file state for nvidia-vgpu-mgr.service: No such file or directory"

- downgraded the failure again to a warning, reversing my initial recommendation to you,
  mostly due to future proofing for the case where NVIDIA fixes this, as in that case we'd
  need to tell users that they should ignore a failure, which is not good – my bad for not
  thinking of this earlier.
