Library missing when mapping named volume to /config

[oceantrail23]

Thank you for this fantastic container! I noticed some unexpected behavior, detailed below. I wanted to bring it to your attention, as I didn't know if this behavior was intended. I believe I have found a suitable workaround, but I am open to suggestions if there is a better way to do it. Thanks!

Unexpected behavior:
Everything worked as expected when using the recommended bind mount, /docker/plex/config:/config. For maximum portability, I wanted to use a named volume to sync this directory with my Google Drive using the rclone plugin, as follows:

services:
  plex:
    ...
    volumes:
      - config:/config
      ...
volumes:
  config:
    driver: rclone
    driver_opts:
      remote: my-google-drive:path/to/config
      allow_other: "true"
      vfs_cache_mode: full
      poll_interval: 0

However, with this configuration, the Library directory is not created or populated (even after deleting and re-creating the container, as I understand it may only be created on the first run).

Workaround:
I was able to manually create another named volume for the Library and map it to /config/Library, which caused it to populate as expected, using the following addition:

services:
  plex:
    ...
    volumes:
      - config:/config
      - type: volume
        source: config
        target: /config/Library
        volume:
          subpath: Library
