Awesome, this makes warm pool support much easier..
Did you get a chance to run this and make sure it works? Not sure if our functional testing covers warm pool or not

I haven't - I believe we have a warm pool TC in the functional tests - was planning to use that to verify. I validated that the IMDS endpoint was returning the expected values on a test instance

Yes, looks like we do.. would probably good to do a quick manual test since bdd tests basic CRUD, but I believe if user data fails for any reason node will not join and test will fail, so it should be sufficient
