> {code}
>    * @param link The path of the link being created.
>    * @param dirPerm permissions to use when creating parent directories
>    * @param createParent - if true then missing parent dirs are created
>    *                       if false then parent must exist
> {code}
> According to javadoc, auto created parent dir's permissions will be dirPerm, but in fact
directory permissions are always inherit from parent directory plus u+wx.
> IMHO, createSymlink behavior should be the same as create, which also inherit parent
dir permission, so the current behavior makes sense, but the related dirPerm parameters should
be removed cause it is invalid and confusing.
