If you want to jail users, than IMO the best way is jailkit :)
(http://olivier.sessink.nl/jailkit/howtos_chroot_shell.html)

If you want to run linux in an chrooted environment, I think you should

(linux from scratch). The LFS manual has very good instructions on how
to create an chrooted environment for linux
