DigitalKiwi: Sure happy to help. I glanced over the volume code and it seemed pretty straightforward. I'm not too familiar with the module structure yet though. Once I figure out how to build nixops with the plugin I can give it a test run
DigitalKiwi: re the nixos-infect -- good to see that some of the more recent images are supported; though I imagine now that DO supports images, that's probably the way forward?
