I'm having a problem I'd like to solve, and at current, the shortest path that I can see is being able to mount an NFS share within /mnt, which in LibreELEC seems impossible as the root filesystem doesn't provide /mnt and is read-only. I'm VERY open to other solutions, but at this point I'm stuck.
Background: I have an extensive media collection that has been curated over many years, and it's currently living on my file server and is shared to various other servers over NFS. The path on ALL other servers is /mnt/fileserver. It has been shared on an airsonic VM (now decommissioned), my local vdi VM, and my jellyfin VM. This matters because inside this folder is a Music/Playlists folder, and it references my music files by absolute path at /mnt/fileserver. Everything works peachy.
My main consumption of media is via LibreElec boxes on most of my TV's, and that is accomplished via the JellyCon plugin. It works fantastic, and I have a home menu with shortcuts straight into the Jellyfin libraries, it's seamless.
The big issue is music. My jellyfin server hosts music, and the Playlists work fine. The web UI works great, and the android apps (Finamp, the Jellyfin app, and Findroid) work fine. The issue is the Jellycon Kodi add-on has no mechanism to play Playlists. They don't show up in the library or anything. It's a bug I've submitted over there.
So, in the interim, I'm trying to find a way to present the media library to Kodi. I can use SFTP and NFS and get the music files to show up, but the Playlists are out as they are hard coded to absolute paths based on /mnt/fileserver and I am NOT redoing that just for this purpose.
So, I'm stuck. If I could create an NFS mount at /mnt/fileserver on the LibreELEC boxes, the whole music library would show up local and I think the Playlists would work as expected, but since / is read-only, I can't do that, and mounts at other paths defeat the purpose I'm trying to solve. I'm open to any ideas; and other than Linux jiggery-pokey to remount / as read-write and create the path (which is likely update unstable) I don't see a good path forward to getting LibreELEC to play my existing playlists?
