Creates a configured plugin path for distributing custom Ohai plugins, and reloads them via Ohai within the context of a Chef Client run during the compile phase.
node[:ohai][:plugin_path] - location to drop off plugins directory, default is
/etc/chef/ohai_plugins. This is not FHS-compliant, an FHS location would be something like
/var/lib/chef/ohai_plugins or similar.
Neither an FHS location or the default value of this attribute are in the default Ohai plugin path. Set the Ohai plugin path with the config setting "
Ohai::Config[:plugin_path" in the Chef config file. The attribute is not set to the default plugin path that Ohai ships with because we don't want to risk destroying existing essential plugins for Ohai.
Put the recipe
ohai at the start of the node's run list to make sure that custom plugins are loaded early on in the Chef run and data is available for later recipes.
The execution of the custom plugins occurs within the recipe during the compile phase, so you can write new plugins and use the data they return in your Chef recipes.
For information on how to write custom plugins for Ohai, please see the Chef wiki pages.
