Scripted installation of Plex Media Server

Hi, I am reading though the script, as I like to understand them before I use them, and have a couple of questions, which I hope you can answer.

  1. The command to create the Jail (line 166) has ${DEVFS_RULESET} on it. I understand the rest but not sure what this is, can you expand my knowledge please by explaining it.

  2. I think I understand that lines 195 & 198 set the Plex MetaData directory to /config, which is where you mount the dataset holding this data, is that right?

  3. Not sure what the directory /configs is used for, can you explain?

  4. The package plexmediaserver_plexpass used to be for Plex Pass users for their additional features, has this now merged into the plexmediaserver package with the plexmediaserver_plexpass just being used as a BETA now?

Thanks,
Jonathan
