Overview

Overrides a method in Capistrano::Configuration::Servers. That method allows for configured default_run_options to override the options defined on the task itself. The problem is it doesn’t do a deep merge, so any option that is a hash ends up being completely overwritten rather than being merged itself. What we’re doing here does break the defined contract for Capistrano, but should be equivalent in non-deep merge scenarios. We need the deep merge in order to specify both a :platform (as a default_run_option) and :primary (as a task option) hash value for the :only option. NB: For simplicity we’re only “deep merging” one level deep, in order to meet our immediate use case.

We shouldn’t make a habit of patching Capistrano in Rubber. But since Capistrano 2.x is effectively a dead project, getting this fixed upstream is extremely unlikely.
