Hey,

Satellite 6.4 upgrade process automatically tries to find macros which has been deprecated and convert them into new syntax for all templates, parameters and lookup keys and values.

  @host.params["parameter1"] -> host_param("parameter1")
  @host.param_true?("parameter1") -> host_param_true?("parameter1")
  @host.param_false?("parameter1") -> host_param_false?("parameter1")

The process uses simple text replacement which will not work in all cases, e.g. when host is assigned to a variable:

  myhost = @host
  myhost.params["wont_work"]

After upgrade to 6.4 please verify all templates, parameters and lookup keys and values for the old-syntax and replace manually. The error that can be thrown for old syntax is:

  undefined method '#params' for Host::Managed::Jail

Changing provisioning template to the new syntax helps to avoid the error.
