[ADE] Has anyone ever gotten this to work?

I don't know how to write this bug, but I have tried to get this feature to work on at least 10 different Ubuntu 18.04 VMs. Clean, machines with just OS disks, machines with OS + Data disks. I've bricked several machines. This thing just never works.

Latest attempt is version 1.1.0.52 - The OS disk is 32GB SSD, so I created a machine with 64GB memory.

**Latest issue is a failure to unmount \oldroot after 10 attempts.**

I really feel like the documentation is incomplete and must be missing some critical step that I am not following. Is the issue with how I am mounting drives? With the processes that are running?

Is there some "prep the machine" checklist that I can't find?

The issue names ADE version 1.1.0.52 on Ubuntu 18.04, using a 32GB OS disk and a 64GB-memory VM, but provides no file or test entry point. Start by reproducing the failure and reviewing the documented mounting and machine-preparation steps; done means the oldroot unmount succeeds without repeated failures.
