Without the use of complex container technologies, giving root access to a chroot is essentially equal to giving root access to the host, so while it's technically possible, I'd very strongly recommend against it. An alternative would be to have another machine on which you'd be happy for that student to have root access and copy the chroot there, so they can modify it, then you copy it back to your server and run ltsp-update-image on it. -- Stéphane Graber Ubuntu developer http://www.ubuntu.com
