Yes, B is some sort of "more specific A". Not easy to explain because they use custom apps, services, and files (and I don't even fully know how they work), but maybe this example will fit: - role A is "web server" - role B is "secure web server" - the same set of resources (packages, users, files, configuration edits...) is applied for both roles, but role A sets some permissions in httpd.conf while role B needs more strict permissions for the same web paths, so they need to use different parameters for the same line in the same file. Maybe inheritance is the way to go? I can put my resource (and related ones) in a separate class with a parameter for the value to be inserted in the conf file, and then create two different classes for roles A and B which inherit the class and override the resource attribute through the parameter. Is that right? Other ways to do this would be to just "propagate" the parameter for the > change to both "role A" and "role B" with default values. > What do you mean? > I am not sure if understood the idea.

I'm provisioning the hosts through Foreman, I need the installation and configuration of the hosts to be automated, based on the classes/roles selected in the Foreman GUI. I do not want to create the custom fact "by hand" on each host. That's why I was thinking about checking the classes applied to the host, as a way to automatically detect the value to be assigned to the fact. > N.B.

I assign puppet classes to the hosts using the Foreman web GUI; either specific classes during tests, or by associating the classes to different host groups and then assigning hosts to groups.
