What is failonfail in this line ?

[shaheena86]

  Puppet::Provider::Command.new(@name, @path, Puppet::Util, Puppet::Util::Execution, { :failonfail => true, :combine => true, :custom_environment => @custom_environment })

Hi - It's been a while since I've looked at any Puppet, but I think it's an argument to
Puppet::Util::Execution which determines whether a command failure bubbles up to fail whatever cause it.

See https://github.com/puppetlabs/puppet/blob/master/lib/puppet/util/execution.rb#L46
