I like restricting tasks to roles, partly out of laziness. I don't need to specify HOSTS or ROLES on the command line as long as I've defined the relevant roles somewhere. It also provides a safety net. Without specifying HOSTS or ROLES on the command line, a task will get run on *all* defined hosts. This can be avoided by restricting the tasks themselves in deprec. A problem with restricting tasks to roles in deprec was that Capistrano complained when I ran a task in an ad-hoc manner without any hosts being defined for the roles it was restricted to. Sometimes I want to run a task on hosts but don't want to add them to a deploy.rb. Editing a file just to use a command line is extra work! e.g. cap deprec:mysql:install HOSTS=foo,bar This problem caused me to remove a lot of role restrictions from deprec over the last year or so. My Capistrano patch (included in capistrano-2.5.0) causes Capistrano to not complain about an undefined role if HOSTS or ROLES are specified on the command line. http://github.com/jamis/capistrano/commit/8badb0c522b38fae9cbe973451472afbddef61cb So, I'm putting the roles back in. - Mike a374e78d6debd6115c99d6f4f919363e4f170d8b Mike Bailey mike@bailey.net.au
