Well, you didn't show how the custom function is actually used there, but I
guess you omitted a statement of the form
$localPaths = prefixPaths('/fuse/common', $resourceDirs)
, right?
I suspect the problem is not with your function. Most likely, the array is
getting flattened after it is returned. In fact, I'd be very surprised if
the value you assign to your File's 'path' property were not flattened. As
far as I know, the ability to declare multiple, similar resources by using
an array as the resource title requires the array to be the actual title.
I don't think you get the same result by assigning an array to the
resource's namevar (nor do I think you should).
So, try this:
# Manage common directories
file { $localPaths:
ensure => 'directory'
}
