Indeed, this isn't going to work. The ${…} style parameter expansion
*only* works within the reclass database. By the time Ansible sees
the reclass data, all such parameters will have been expanded.

This on the other hand /should/ really work, but I honestly won't be
surprised if it does not. As I've said multiple times before,
Ansible is quite hackish in many places, and especially its usage of
templating is very inconsistent.

Have you tried accessing the variable from within a template in
a playbook? If that does not work, then there's a real problem,
possibly with reclass. But if that works, then the best you can do
is either accept that it doesn't work with the debug module, or take
this on with the Ansible community.
