This just sounds silly to me. Why in the world would you want to
duplicate the whole system for each user, as you are discovering you
have to do. If you have data that is really that sensitive, buy a new
computer. A chroot jail just is not strong enough to keep out a
determined adversary and is too much of a pain to set up and use.
You would have to copy over /etc/passwd at least, plus probably the
whole /etc/pam.d and libpam etc stuff.
