[chef] Easier symlink management?

[Peter Norton < >]

I'm migrating installations over to chef that currently do a lot of
symlinking.  The actual symlinks make sense, but don't adhere to the
rails/capistrano layout deployed in the chef documentation for the
deploy mechanism.  It seems to me that the deploy mechanism is more
than I want - I'd like to be able to do

symlink_dir "foo" do
  user myuser
  group mygroup
  obj_types [ 'd', 'l', 'f' ]
  source /source/filesystem/path
  dest /destination/filesystem/path
end

and have all files, directories, and symlinks be symlinked from
src->dst. Instead it seems that I have to do this:

  bash "create_bin_symlinks" do
    # Binary symlinks don't get directories linked in.
    user 'user'
    group 'group'
    cwd dst_dir
    code <<-EOBASH
    for item in $(ls #{src_dir}) ; do
      if [ -x #{src_dir}/$item ] && [ ! -d #{src_dir}/$item ] ; then
        [ -h #{dst_dir}/$item ] || ln -s #{src_dir}/$item #{dst_dir}/
      fi
    done
    EOBASH
  end

and tailor this a bit for each file type that I want, which means I'll
be littering a dozen cookbooks and 3x that recipes with this sort of
thing.

How could I add to the DSL to create the feature I described here?  In
fact, how could I do it such that the obj_types could be augmented by
passing in a callback to a filter function so instead of just types I
could use any property of the file to determine whether or not to make
the symlink in the source and dest?

Thanks,
