Is the restricted shell really secure?

	It make the chroot() call not
go back past the 'new' root area you
use the following program.
main()
{
	unlink("DIRECTORY/..");
	link("DIRECTORY/.","DIRECTORY/..");
}
	I think that is right. This
will make sure there is the right
number of links and will make '..'
point to '.'.
