I believe also that only the superuser can create a hard link
for a directory:

	$ mkdir foo
	$ ln foo bar
	ln: foo: hard link not allowed for directory
	$ su -c "ln foo bar"

I have no idea what the result of that command is. Probably
you'll just trash the free list and mangle your superblock.
But the outcome might be something particularly unpleasant,
so before I got out the big hammer, I'd, uh, wait for the SGI
journaling filesystem to be integrated into the 2.2 kernel.
