RancherOS and Longhorn


I was watching the video on Longhorn and was curious how it will integrate with RancherOS and/or Rancher (both 1.x and 2.x) At the time of the video, Longhorn only created sparse files on top of other filesystem(s). Though it was mentioned that it would likely be possible to pass entire disks.

Will this be something you can configure in RancherOS via cloud-config.yml? (Just pass all disks to Longhorn?)
Will there be a way to manage a hosts / disks in Rancher 1.x (or 2.x)?
