Request for best practices since plex support is quite limited (and frankly rude)

[witcheslive]

Had to clean up the ol' system drive today and one of the biggest things taking up space by far is my plex media library data, so I went around looking for how it might be movable. After... far too many click holes (thanks search engines for being terrible) found a thread where plex staff were being rude to someone for the high crime of running mint with an oblique mention to the only documentation that seems to exist for plex for this task, which is:

"Moving Plex’s metadata (Library) directory on systemd based systems"

Void help me this kind of thing is why I don't run systemd, it seems fine, I just really don't like the demands I use it. But I digress. Is there a way to update the location of the media library data that won't get clobbered with updates and is otherwise in line with best practices?
