[chef] Re: Omnibus 4.0 and Ohai question

Eric,

You can use "ohai['platform']" (with lowercase "o") in your software definition:

https://github.com/chef/omnibus/blob/master/lib/omnibus/project.rb#L681-692

https://github.com/chef/omnibus-software/blob/master/config/software/ruby.rb#L77

I am coming back to Omnibus and updating some software definitions
having not used Omnibus in 6 months.

I used to be able to reference Ohai['platform'] but that returns a no
method error on Omnibus 4.0

Error:

    config/software/package.rb:20:in `evaluate': undefined method `[]'
for Ohai:Module (NoMethodError)

Line causing error:

    version_name_string =
"#{Ohai['platform']}-#{Ohai['platform_version']}-#{Ohai['kernel']['machine']}-#{version_string}"

So what do I need to do to reference Ohai data in an Omnibus 4.0
software definition?

I do know in some cases there are chef-sugar helpers like `windows?`
that can be used to switch on platform conditions.  I couldn't find
relevant documentation, and if someone could point me at an example it
would be kindly appreciated.
