Makes sense. I wonder if we need all of "-dils", but it's not clear to
me which syscalls actually trigger the FreeBSD lazy-update behavior. I
guess probably it's stat()ing the directory, so "ls -ld" would be
sufficient (and that's implied by the examples in 6b7728db81).
But I doubt the extra options would create a portability problem, so I
think it's fine either way.
