[gentoo-user] why forbids making hard link for directory?

[Shaochun Wang]

I know it forbids making hardlink for directory in current filesystem,
but i don't know why? Can you tell me why?

You could make a cycle (like directory placed inside itself) that would
be undetectable and all the nice utils like find, grep -r, cp and so
would work forever traversing them.
