It does nothing of that, I use it a lot in my modules and it solves many problems.

It not so undocumented. You don't just convert a array to a string, you get an empty separator ['a', 'b'] is converted to 'ab', for what I saw in many of my mistakes. So someone was thinking about my use case and add the code to have a ' ' separator for the rpm command. > > So don't do that. > > > John -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
