[chef] Re: stopping recipe execution early

[AJ Christensen < >]

To expand; apologies: occasionally we'd skip the entire execution of a
recipe depending solely upon the results from our Discovery [0]
library cookbook.

A common (gated) execution pattern is:

return unless discovery_search("a_servers_role_that_ineed",
  :empty_ok => false,
  :environment_aware => true)

Cheers,
