sorry to say this, but this looks hell of wrong to me.
Don't do this based on variables. Don't even think of doing that.
Variable scoping already has enough caveats as it is. You're obfuscating
your end.
What you probably want to do is this:
class child inherits parent {
File['...'] { source +> [ "/path/to/second" ] }
}
You override the resource's parameter using plusignment syntax.
That would be sort of acceptable, but are you sure this facilitates a
folder merge? Afaik, specifying multiple sources will make puppet choose
the first that turns out to be valid and ignore all others.
If you're in 2.6, according to the style guide, you should be using
class parameters for thise instead of class inheritance as outlined above.
HTH,
