A cookbook can be designed to support the distribution of templates across platforms, while ensuring that the correct template ends up on each system.

The pattern for template specificity depends on two things: the lookup path and the source.The first pattern that matches is used: The chef-client caches a template when it is first requested.On each subsequent request for that template, the chef-client compares that request to the template located on the Chef server. A template can be built in a way that allows it to contain references to one (or more) smaller template files.(These smaller template files are also referred to as partials.) A partial can be referenced from a template file in one of the following ways: that will be made available to the partial template file.Vernon Erb was determined to be a truck driver, despite his father’s wishes that he continue his schooling.
