Completely unscientific poll: cfengine, puppet, other?

I wonder if anybody is using Rex? We have been using Rex
(https://www.rexify.org) with much satisfaction. It is similar in
concept to Ansible, ie push, not pull.

Configuration instructions are via so-called Rexfiles. They are written
in a small DSL but can also contain arbitrary Perl, and that where it
shines, perhaps because we use Perl a lot.
