ok, that's great. Thanks for the help.
The puppet-docs it says: "*Modules are how Puppet finds the classes and
types it can use* — it automatically loads any
class<http://docs.puppetlabs.com/puppet/2.7/reference/lang_classes.html>
or defined
type<http://docs.puppetlabs.com/puppet/2.7/reference/lang_defined_types.html>
stored
in its modules."
With this in mind, if "*if *defined(Class[ ])" checks for classes.. and in
my case 'supervisor::service' is as you mentioned not a class but a define.
Is there an equivalent like "if defined(Define[ ])" or is best practice to
continue using "if defined('supervisor::service')" to just check for
anything of that name.
Thanks again
