Example text

As we explained in Chapter 1, each resource is made up of a type, title and a series of attributes. Each resource’s attributes includes its “name variable,” or ”namevar,” and the value of this attribute is used to determine the name of the resource. For example, the Package and Service resources use the name attribute as their namevar while the File type uses the path attribute as its namevar. Most of the time we wouldn’t specify the namevar, as it is synonymous with the title, for example in this resource: file { "/etc/passwd": … } We don’t need to specify the namevar because the value will be taken from the title, "/etc/passwd".
