A specific example I think will be of much help. Some ideas: 1) Is "role B" just a more specific "role A" or they aren't so much related. You can use inheritance if they are and change the file/define you are interested in. Although inheritance is almost always abused in this setup it is OK. > > > > Can't it just be a single class with a parameter moved to hiera or > > > Er...

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. > > something else?

I am not saying that you have to create a dependant fact but just to set a fact with the value you want to change. So let's say you want to have a database connection URI. Role A sets it to something by default and Role B sets it to something else. You can specify the wanted connection URI on the host with custom fact. N.B. Can you also tell us how do you assign the roles for each host because that might help us be more specific with a solution. -- Nikola -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
