symlink pointing to itself

[Rafael Torres]

Hi all,

I've accidentally created a symbolic link that points to itself :

[rtorres@rtorres tmp]$ ln -s tst tst
[rtorres@rtorres tmp]$ ls -la tst
lrwxrwxrwx 1 rtorres rtorres 3 Feb  1 11:59 tst -> tst


I've search in the list archive and didn't find any discussion about it.

Is it a small bug in symlink() or is there any purpose for such "feature" ?
