Here is a description of my problem:

I've a Puppet class class_A and 2 environments env_A and env_B.

Here is a description of my class present in env_A AND env_B:

class class_A ($param_A) {
...
}

I want to upgrade the definition of the class in env_B only with the following:

class class_A ($param_B, $param_C) {
...
}

So I upload my new module definition to the puppetmaster and trigger an import on Foreman.

Now, if I check in Configure > Puppet classes > class_A > Smartclass parameters I can see that:

• My new parameters param_B and param_C are present for the environment env_B only
• The parameter param_A is still present in env_B

It is annoying because if I try to a Puppet run on a host from env_B, it can't run saying unable to locate parameter param_A.

I had to delete the param_A from my Puppet classe, which also removed the parameter from the environment env_A causing error in the puppet runs for that environment.
