http://0pointer.de/blog/projects/serial-console.html gives details of 
how the gettys are configured in systemd. From a cursory glance, you can 
take getty@.service, clone it to, say chroot-getty@.service, and modify 
it to run the getty in your chroot, then enable and start 
chroot-getty@tty8.service.
