Tested trunk checkout of today installed on Ubuntu 7.10 Both ssh-chroot and Jailkit enbaled don't seem to prevent a ssh user from going out of their homedir..
- For SSH-Chroot, you will have to recompile your SSH daemon with the chroot patch. - Foe Jailkit, there has already been a bug reported: http://bugtracker.ispconfig.org/index.php?do=details&task_id=116
