link of directory

[Francois Bronsard]

I am using an unix system V that doesn't allow symbolic link to directory.
I was told that I could get around that by using the system call link if I
am root. However this will create an hard link, so I was also warned that
this might be a dangerous idea. My question now is: How dangerous?
Specifically I only want to add to my top directory a link to Filecabinet
(the reason being that I am using a MsDos program that doesn't understand
lowercase characters so it cannot find the directory Filecabinet, so I
thought of adding a link to it called FILES to be able to access
Filecabinet). In that specific case what are the exact dangers and problems
with creating a second hard link to a directory? 
(I emphasize this specific case because I know that one could for example
create a loop of links which, I have no doubt, would make the system crash
sooner or later).

Please reply by e-mail, I don't read this newsgroup often.
