"Watching for new files in real time"

I suppose “real time” is relative, but it’s definitely not real time enough IMHO. Honestly no idea if it ever updates? I suspect it is because my music is stored on a NAS and Roon (running on Linux on a NUC) sees it over NFS. I’ve done things like check /proc/sys/fs/inotify/max_user_watches, etc and still doesn’t work. Per this thread it sounds like the official Roon response is “sorry, not our fault”: Roon is not watching for new files in real time

Other than manually kicking of a re-scan every time I add music, is there some way to get Roon to scan automatically on a pre-defined schedule (like a cron job?).
