[chef] Re: Re: Determining if a chef-client run is an initial chef-client run through handlers

[Roger Lam < >]

Hi Mike and Chefs,

I found the 'registration_completed' method under the EventDispatch class.
http://www.rubydoc.info/github/chef/chef/master/Chef/EventDispatch/Base:registration_completed

There's a section in the Customizing Chef book that overrides event
methods and injects them with start handlers but that's not exactly
what I'm looking for. Ideally, the code would live in a single
cookbook and not spread to the client.rb or a separate gem as start
handlers require.

I'd love and really appreciate any ideas. Thanks!

Roger
