-  For historical reasons (Debian Lenny's version of APT did not support the use
-  of the `preferences.d` directory for putting fragments of 'preferences'), this
-  module will manage a default generic apt/preferences file with more
-  recent releases pinned to very low values so that any package
-  installation will not accidentally pull in packages from those suites
-  unless you explicitly specify the version number. This file will be
-  complemented with all of the preferences_snippet calls (see below).

+  managed by Puppet. By default, this parameter is set to `true`.

-  template located in your `site_apt` module, and set custom_preferences with the
-  content (eg. custom_preferences => template('site_apt/preferences') )
