Things look good to me so far. I'm not able to replicate the CI build-and-test failures on my local workstation so those might be transient failures.

Looks like sled-agent is failing here on the deploy task:

sled-agent: Failed to delete all XDE devices

Caused by:

Local deployment is working so it looks like the deploy task will work once we pull the new xde / update the illumos image in ci
