Douglas,
If you don't use a conditional somewhere, how are you going to decide
what resources are declared on what clients?
In that blog example, the classes are loaded based on the value of a
fact reported by the Puppet client, in some ways "more reliable" than a
variable defined in a Puppet master manifest. It's also not that bad a
practice to conditionally include on variables declared at the top level
(node.pp) - avoids variable scoping issues, a number of people on the
list do that.
Using sub classes based on operating system also gives you the added
advantage of tracking down problems sooner, a Puppet error will look like:
Foo::Redhat::File["foo.conf"] ...
What approach would you like to see, conceptually? Maybe someone's done
something similar with an ENC.

So... I'm thinking about how to have puppet manage different
operating systems. It's one thing to use a selector to determine
the value of specific resources attribute, but what do you do when
a file may not exist on a specific O/S? You can't use a selector
in this case.
I really don't like the approach described here either...
http://m0dlx.com/blog/Puppet_manifests__a_multi_OS_style_guide.html
...where classes are loaded dynamically based on the value of a
variable.
What would best practice indicate?
Doug.
