[chef] Re: Re: Re: Ohai Plugins Available when evaluating attributes.rb?

[Steven Danna < >]

Hi Douglas,

Provided that the plugin is in Ohai's load path, it should get loaded
along side all of the built-in plugins.  The one exception is the very
first run of chef-client on a node. Since many people depend on a
cookbook to put the custom ohai plugin in place.  If you are putting
the ohai plugin in place in a recipe and reloading ohai (even if you
move those resources into the compile phase), then your attribute will
be available in the recipes but not in the attribute files since the
recipes are evaluated after attribute files inside the compile phase.

One option to get around this would be to make sure that *required*
custom plugins get put on disk during your bootstrap process.

Sincerely,

Steven
