I have a question about the dangers of having two hard links to the same directory in Unix System V. Basically, I cannot do a symbolic link (because my version of the system is too old), so I was told that I could use the system call link() to create a hard link to a directory. However, I was warned that such a thing is dangerous since it might confuse the file system (specifically, the programs find and fsck/icheck/ncheck). Now my question is : "How dangerous is it really?" In particular, all I want to do create the following structure : $home / .. \ ... / \ FILES \ \ \ \_______files ... (The link between FILES and files is the new link that I want to have). So what problems can such a link cause to the files systems? Francois
