It's not likely to be a link to another directory. Even as root on my box I can't create hard links to directories. The output is:
# ln -d real linked
ln: creating hard link `linked' => `real': Operation not permitted
The man page for ln has this to say:
-d, -F, --directory
allow the superuser to attempt to hard link directories (note: will probably fail due to system
restrictions, even for the superuser)
You could copy an existing directory and modify the contents, but it's better not to use the gui as root.
