The last few updates of PMS on my linux box seem to overwrite plexmediaserver.service in /etc/systemd/system/multi-user.target.wants .
As a result, my chosen user & group for plex get overwritten each time. Am I setting this in the wrong place, or should I be doing something different?
/lib/systemd/system/plexmediaserver.service is the as-distributed master service file
Systemd creates a symbolic link to it, located in /etc/systemd/system/multi-user.target.wants when it is enabled for automatic startup
Systemd overrides / customizations to how Plex operates should be placed in /etc/systemd/system/plexmediaserver.service.d/override.conf per systemd specifications.
