Nope.  *Only* by the kernel.  There's no way of writing into a directory
file from a user program except by openning the special file for the
file system, traversing the hierarchy yourself, and manually zapping a 
block in the directory.  And, if you have to allocate a new block?  Well,
forget it.

The "link" system call will do what you want if you're root, unfortunately, 
fsck will probably bitch.
