@emmanuel - few questions:

  • I take it when you source another unit file and add a [Service] block this override that section ..
  • should i provide the same Docker parameters that CoreOS provide - to get it to perform like "normal"
  • I should ExecStart to the path of the new binary right?
  • Have you tested on the recent stable version to confirm if this still works?
