You’re lucky Juan!

The application is already written for you!

It’s called Capistrano.

Capistrano would be a good solution if you wanted  
to run a program (any type of program, not necessarily  
Rails) on groups of machines simultaneously.

Hi Tom,

Would Capistrano be the good way to generate bind confs from a db for a  
bulk of domain names ? I’d like to run a task each 15 mins to dump db  
data if changed, and reload bind conf.
