"operatingsystem" fact has been removed, causing this module to fail on all Macs

[zbentley]

Puppet recently removed the operatingsystem fact. This causes this module to fail thus on all Macs:

This Module works on Mac OSX only!.

The code in init.pp should be updated to check $facts['os']['family'] == 'Darwin' instead.

Affected folks can temporarily work around this issue by creating a back-compat operatingsystem fact (in any module: lib/facter/operatingsystem.rb) like this one:

Facter.add('operatingsystem') do
  setcode do
    Facter.value('os').fetch('family')
  end
end
