Issue #4189 has been updated by Johan Holmberg.


GNU cp has the -l option, so I think the proposed method is similiar to "cp -lr" on Linux systems.

Feature #4189: FileUtils#ln_r

 I wrote a method for FileUtils to do recursive hard linking. It works just like cp_r but links instead of copies.
 
 The code can be found along with the pull request I made to ruby/ruby on Github:

 It's a pretty handy method for "staging" read-only files. For example I've used it to stage test fixture files in a tmp testing location and I've used it collect together a set of files for packaging into a tarball.
