New Revision: 51070
URL: https://svnweb.freebsd.org/changeset/doc/51070

Log:
  we need to delete the target symlink first before we can create it
  
  This solved the issue with symlinks to directories.  The semantic
  of `ln -fs' is special if you run it for directories twice, e.g.
  
  mkdir from
  ln -sf from to
  find . -name from -or -name to
  ./to
  ./from
  
  now run it again
  ln -sf from to
  
  find . -name from -or -name to
  ./to
  ./from
  ./from/from
  
  ls -l from
  total 1
