You misunderstood the concept of a namevar. The namevar of the
file resource is `path`, for the exec resource it is `command`, for a
service resource it is `name` and so on.

Here is an example where I set the namevar.

  file { 'sshconfig':
    path   => '/etc/ssh/sshd_config',
    ensure => file,
    mode   => '0600',
  }

So I set the namevar (path) explicitly.  Note that `namevar` is more
from the viewpoint of a resource type developer.  In a manifest it is
just a parameter of a resource.

If you do not specify the namevar explicitly, it is the text before the
first colon, so in other words the title of the resource.

So when I write

  file { '/etc/ssh/sshd_config':
    ensure => file,
    mode   => '0600',
  }

I did not specify the path of the file directly. I just set the title
and so path is implicitly /etc/ssh/sshd_config in the example.

However you cannot access the path parameter as a variable in your
manifest. It just happened that there is a fact that is named `path` so
whenever you use $path you will just query that fact.
