Yeah! I think is a great feature for long operations, having a minimun output is better to have nothing for a while... :) > The idea maybe useful for tasks which are kind of long and user wants to get > some notification about what is going on on the other side.

Sorry for the delay, this implementation seems very nice. I would like to test it before give suggestion but for me it's ok your approach. I'd also like to see the performance on huge number of machines and how much we lost using it. What I'm thinking is how is it when you run puppet on a lot of machines (I think puppet is not so fast so we can breath! :)) Thank you again to implemented it :) Cheers Luca _______________________________________________ Func-list mailing list Func-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/func-list
