I have a Ubuntu NUC which I just use as a Plex server, and when I installed Ubuntu on that I created a user named "plex", which is a full fledged user with home folder, login etc. When I installed PMS of course the plex user was used as the user for PMS, but now I read that in the standard installation the plex user doesn't have a home folder in the /home path and doesn't have login.
Do you think I might have issues (security?) with my setup? It was quite convenient because I didn't have to fiddle with users and groups to access my data, being the only user of the server and logging in as "plex" user when I need to work remotely on the files. Oh and when I say "remotely" I mean from a ssh shell in my local network, I don't have plex remote access or ssh outside my home network enabled.
