h1. Templates

The following functions and macros can be used within templates.  These are guaranteed to work via the safemode rendering, to ensure a template can do nothing harmful.  With safemode disabled ($$ADD instructions here$$), other macros may work, but are not supported at this time.

h2. Accessing Templates

There are two ways to render a template, based on a single host, or based on a Hostgroup.  The host or hostgroup provides all the details with which to render the template.  

h3. Host-based Rendering

h3. Hostgroup-based rendering

Allows any template to be rendered for any Hostgroup.  When rendering using a hostgroup, @host is actually the hostgroup instead of a defined host. The default values for the hostgroup are used for templated values.  This means if a value is not set in the hostgroup, you may get an error when rendering the template.  To access a template using a Hostgroup to render, simply use this URL:

/unattended/template/Template Name/Hostgroup Name

For example, a hostgroup of name Finance, and a template named WebServerKickstart could be rendered using the url:

/unattended/template/WebServerKickstart/Hostgroup

h4.  PXE Menus

Pxe Menus can be deployed to smart proxies from the Config Tempalates.
