阻止厨师创建递归符号链接

Question

我将deploy资源与symlink_before_migrate({'folder' => 'folder'})一起使用，并且正确地将current/folder与shared/folder相关联，但也创建了链接到shared/folder/folder的链接shared/folder

ls -alh /proj_dir/current/folder/
drwxrwxr-x 2 ubuntu ubuntu 4.0K May  9 07:39 .
drwxrwxr-x 9 ubuntu ubuntu 4.0K May  9 07:39 ..
-rw-rw---- 1 ubuntu ubuntu 1.2K May  9 07:39 file1
-rw-rw---- 1 ubuntu ubuntu 1.3K May  9 07:39 file2
lrwxrwxrwx 1 ubuntu ubuntu   41 May  9 07:39 folder -> /proj_dir/shared/folder

如何阻止Chef创建递归符号链接？
