Plugin @id or path for <storage> required when 'persistent' is true

I have a config like:

    <source>
      @type systemd
      filters [{ "_SYSTEMD_UNIT": "kubelet.service" }]
      pos_file /var/log/gcp-journald-kubelet.pos
      read_from_head true
      tag kubelet
      @id in-systemd-kubelet
      <storage>
        @type local
        @id in-systemd-kubelet-storage
        persistent true
      </storage>
    </source>

and getting the following error:

2017-09-13 09:18:25 +0000 [error]: config error file="/etc/fluent/fluent.conf" error_class=Fluent::ConfigError error="Plugin @id or path for <storage> required when 'persistent' is true"

If I remove the @id from the storage section and add the path it all works fine.

If you set persistent true it is required to give a path to the file used to store the cursor...

A working example is given in the README, could you explain what you expect to happen with this configuration? since it just looks invalid to me.

How about the following configurations?
Because storage plugin does not handle file path with @id.
Instead we can specify it storage directive's attributes.

    <source>
      @type systemd
      filters [{ "_SYSTEMD_UNIT": "kubelet.service" }]
      pos_file /var/log/gcp-journald-kubelet.pos
      read_from_head true
      tag kubelet
      @id in-systemd-kubelet
      <storage in-systemd-kubelet-storage>
        @type local
        persistent true
      </storage>
    </source>

@errm I was just confused because of the error message saying @id or path so I expected I was able to set @id but @cosmo0920 gave the answer it seems - thanks :)
