Cannot host ec2 instance on root domain

[justinlovinger]

Given deployment.route53.hostName = domain-name.root, running nixops deploy gives error "Exception: hosted zone for com not found".

The full exception is

webserver..> sending Route53 DNS: example.com A 18.218.14.24

I think I found the relevant line of code. The hosted zone is obtained by stripping the first part of the DNS host name, but if the DNS host name is the hosted zone itself, then it doesn't match.

Is there any reason to strip the first part of the host name? It looks like the code already checks a subset of the host name parts when matching against a hosted zone. All that stripping the first part of the host name does is ensure you don't add a record to a hosted zone that exactly matches the host name, but I'm not sure why that would be desirable.

If I had to guess, I'd say that line probably could have changed when this commit was made.
