That's not what I meant. I was saying, --skip-symbolic-links and
filesystem support of symbolic links are unrelated.

If --skip-symbolic-links was not specified, a filesystem can support
symbolic links or not support them. In the latter case, I think, InnoDB
technically still could use DATA DIRECTORY, even if MyISAM cannot.
