The unit media.mount does not exist anymore in the recent system version.

After=*.device would only work if the device is already there, and can
be included in the transaction, but then the After= should have no

Maybe this works:
  After=local-fs-pre.target
and hook it into
  /usr/lib/systemd/system/local-fs.target.wants
