You're looking for tmpfs and pivot_root. The latter is a hack that's needed
only because of kernel threads, if you're the only process chroot() and
chdir() should be enough.
Too bad, if there's a process which is in uninterruptible sleep, things get
more tricky, and I guess that's the main reason why such a solution wasn't
implemented already.
