Is it possible to make a module a dependency? We have a "base" module that contains packages, configurations, etc, that should be processed before other modules, and I''m looking for a way of enforcing a dependency on everything in the base module without having to explicitly list each package, etc. Thanks, Keith --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Is this what you are looking for?
class foo {
...
}
class bar {
package { "test":
require => Class["foo"],
}
}

It''s safest to put everything you want to run inside the class declaration and include it at the right point. If you put code in init.pp but outside the class declaration, I think it will be evaluated at the moment the class is autoloaded, which might not do predictable things. -- Bruce If the universe were simple enough to be understood, we would be too simple to understand it. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.

I''m still banging my head against puppet''s idea of what a class is (as opposed to the OO concept) but one thing puppet has no problem with is making sure that one thing is evaluated before another. Whatever you are trying to do with inclusion, importing or inheritance or some combination of those. -- Bruce I object to intellect without discipline.

Luckily, one often already has a dependency chain within that class, so you only need to add dependencies to a few of those resources. If you, e.g, have: class x { ... } class y { t1 { r1: ...; } t2 { r2: ..., require => T1[r1]; } t3 { r3: ..., require => T2[r2]; } ... t17 { r17: ..., require => T16[r16]; } } and want all of the resources in class y to depend on class x, you only need to add a ''require => Class[x]'' to the r1 resource, since all of r2..r17 already require r1. /Bellman --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Would it be appropriate to create a wishlist item that a module depends on another (module|class)?

A module has no real existence of it''s own, within puppet; it''s just a convenient way of bundling manifests and files together. What do you expect this dependency to *do*? Custom-build functions aside, the code within module manifests will take effect when the relevant class is included, for code within class definitions, or loaded/imported (for code without). Unless you have some extra mechanism in mind, I''m not sure what dependencies could achieve. -- Bruce A problem shared brings the consolation that someone else is now feeling as miserable as you. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.

I have to add that to one of the elements of this class, and the only way to ensure that all of class Y is executed before any of the current class is to have every element of the current class ultimately depend on class Y, either directly or indirectly.
