Would be nice if this worked on Windows too. :)

That will be added with the Link class.

   var args = [ symbolic ? '-s' : '', dst, link ];
   var script = 'tests/standalone/io/ln.sh';
   if (!new File(script).existsSync()) {
     script = '../$script';
   }
   Process.run(script, args).then((result) {
     if (result.exitCode == 0) {
       callback();
     } else {
       throw new Exception('link creation failed');
     }
   });
 }
