Plex Media Permissions for Linux Noobies

There is no problem with being a noobie and I do not use the term to sligtht or disparage anyone.

This is a way to setup your permissions for running Plex in Linux. Different folks may use different methods.

The permissions concepts provided here apply to OSX, but the users and groups are controlled and modified differently, so much of this will not work properly. I think the command is dscl, but that could be out of date.

There are many ways to setup your permissions scheme in Linux, this methodology describes a way to do it, not everyone will like it, but it works for me, so whatever.
