Generally, I find specific class dependencies are something to avoid. The only place I tolerate them is in "role" classes, which is where I usually set up any dependencies between modules that are required, and there I don't need to use defined() or tagged() to check them, because I know precisely which classes have been included. Every time you add a dependency to a specific class, you cause problems for the person who finds a need to creat a new class that inherits from it. That person will often be you and kicking yourself is not rewarding. Looking at my manifests and modules, the *only* places I have a dependency on a named class is in my site::role classes and in the samba::packages class where the named classes are internal to the samba module and contain collections of packages (and their dependencies) relevant to specific versions of Samba. -- Bruce Explota!: miles de lemmings no pueden estar equivocados. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
