The key that is used is the return value of get_operating_system().

It is also possible to add an after hook like this:

 task "add-repo", "server1", "server2", sub {
   repository add => myrepo => {
      Ubuntu => {
         url => "http://foo.bar/repo",
         distro => "precise",
         repository => "foo",
         after => sub {
              # import gpg key
         },
      },
      Debian => {
         url => "http://foo.bar/repo",
         distro => "squeeze",
         repository => "foo",
         after => sub {
              # import gpg key
         },
      },
      CentOS => {
         url => "http://foo.bar/repo",
         after => sub {
              # import gpg key
         },
      },
   };
