Loki server error log option

I’ve recently begun playing with a small Loki setup and have a question about capturing Loki server error logs. I currently run Loki via a systemd ini script that just redirects stdout/stderr to a log file but it requires a bit of a cumbersome execstart command as the version of Systemd in Ubuntu 18 doesn’t support appending to output files using the available output redirection parameters.

Does Loki have a built-in option to specify a file for log output, or is my current method the only option? I had a look at the options available using loki-linux-amd64 --help but I don’t see anything there.


Just bumping this in the hope it might get a response.
