- Remove /mnt/storage/media from systemd.tmpfiles.rules (it's a ZFS dataset mount point)
- Add ExecStartPost to set proper permissions on ZFS-mounted media directory
- Update NFS research documentation with ZFS integration best practices
- Add section explaining ZFS mount point vs tmpfiles.rules conflicts
This resolves the potential conflict where tmpfiles tries to create a directory
that ZFS wants to use as a mount point for the storage/media dataset.
- Create shared media-group.nix module with fixed GID (993)
- Add both geir and sma users to media group for shared NFS access
- Update NFS server configuration to use root:media ownership with 0775 permissions
- Convert all media services to use media group instead of users group:
- Jellyfin, Calibre-web, Audiobookshelf, Transmission
- Enable group write access to all NFS shares (/mnt/storage/*)
- Maintain security with root ownership while allowing group collaboration
This resolves NFS permission issues by providing consistent group-based access
control across all media services and storage directories.
