Hey. While we have no solid plans in motion for additional core distributions we are big fans of Rancher and RancherOS internally. We've had the guys from Rancher in the office more than once to give demos early on but did not add it at that time because it was still in a pretty early alpha state. I personally am a big proponent of RancherOS being adopted as a DO core distribution and will continue to advocate for it inside DO. Lending support to the Uservoice item is a great way to let our product team know of the interest for it.
Please let me know if you do add it. We've cut ourselves out of client DO accounts using the team features to allow customers to have their own machines, and DigitalOcean accounts. CoreOS, docker and rancher represent opportunities for us to manage those remotely (right now it's ansible and SSH). Rancher seems to have point-and-click features which is even easier for us to grow our team as well as provide value to customers.
+1 from me too! It would be really great if there would be something else to use RancherOS besides Amazon AWS.
