I'm a little confused by how custom ohai plugins should be "deployed" on the target servers on which they are required. The docs say in order to install the plugin, you create an ohai directory in the cookbook, and move the plugin in there.
When I create a cookbook with this
ohai directory (and no recipes) and add this cookbook to my policy, I receive an error
Error: Failed to generate Policyfile.lock Reason: (ChefCLI::CookbookDoesNotContainRequiredRecipe) The installed cookbooks do not contain all the recipes required by your run list(s): Cookbook ... is missing the following required recipes: * default
When I add an empty recipes/default.rb file, the policy gets created, and when it executed, the cookbook is synchronized with ohai/plugin.rb file in the cache, the runlist shows the plugin default recipe and the plugin ran.
So, is this the correct way to deploy an ohai plugin to all servers using a policy, using an empty default recipe?
