Capistrano task to use relative symlinks instead of absolute.

gistfile1.rb

require "pathname"

namespace :deploy do
  task :create_symlink, :except => { :no_release => true } do
    deploy_to_pathname = Pathname.new(deploy_to)
    
    on_rollback do
      if previous_release
        previous_release_pathname = Pathname.new(previous_release)
        relative_previous_release = previous_release_pathname.relative_path_from(deploy_to_pathname)
        run "rm -f #{current_path}; ln -s #{relative_previous_release} #{current_path}; true"
      else
        logger.important "no previous release to rollback to, rollback of symlink skipped"
      end
    end

    latest_release_pathname = Pathname.new(latest_release)
    relative_latest_release = latest_release_pathname.relative_path_from(deploy_to_pathname)
    run "rm -f #{current_path} && ln -s #{relative_latest_release} #{current_path}"
  end
end

A Capistrano 3 equivalent would be cool!
