Thanks Athos for flagging this,
you are right if we do not fix it now for Bionic it won't be fixed at all.
But OTOH no one except internal people have revisited this for ages, and being only cosmetic (the service is up and running fine) this won't make the last minute (in the release lifecycle) SRU acceptance especially given the discussions around how it was resolved.

Upstream isn't very happy with the resolution [1] and I'd more lean to
even challenge/reconsider if we might drop this in new versions - this
is 3 years old maybe it is a non issue nowadays.

If someone thinks this is a wrong assumptions please speak up, outline why it is important to be fixed in Bionic in a way that will most likely also convince the SRU team to accept the risk.
Otherwise I'd call this a win't fix for Bionic too.

Bug description:
  [Description]

  Nginx logs an error when started on a machine with a single CPU:

  systemctl start nginx
  systemctl status nginx
  ● nginx.service - A high performance web server and a reverse proxy server

  May 14 19:35:03 ngx systemd[1]: nginx.service: Failed to read PID from file /run/nginx.pid: Invalid argument
  May 14 19:35:03 ngx systemd[1]: Started A high performance web server and a reverse proxy server.

  Bumping the number of CPU available makes the error disappear. This is
  reproducible on VMs and containers.

  Lastly, the PID file is properly created and matches the PID of the
  master process.

  [Workaround]

    sudo mkdir /etc/systemd/system/nginx.service.d
    printf "[Service]\nExecStartPost=/bin/sleep 0.1\n" | \
      sudo tee /etc/systemd/system/nginx.service.d/override.conf
    sudo systemctl daemon-reload
    sudo systemctl restart nginx
