Jellyfin Permission Problem

ntfs mounts need to have their permissions set at mount time. You aren’t setting any here. Read this for the correct way to do that. That is because ntfs doesn’t support POSIX(linux-style) permissions without a bunch of special handling. That means chmod, chown and friends won’t work.
