[chef] Re: Re: Re: Managing package preferences within chef (Debian, Ubuntu, RHEL, etc.)

Turns out Heavy Water has a cookbook for this too:

https://github.com/hw-cookbooks/package_installer

  override_attributes(
    :package_installer => {
      :packages => {
        'vim' => nil,
        'mailutils' => {
          :version => '2.2'
        },
        'emacs' => {
          :action => :upgrade
        }
      }
    }
  )

Funny stuff.

Cheers,

AJ
