Put each subaccount one per line into /etc/shutdown.deny then reboot.

Dear list,
Often there are multiple users working on my multiseat [1] system, some of
them are kids and they are not paying attention if someone else is logged in.
They can shutdown the computer even if someone else is logged in and have an
active session.
Is it possible that only root can shutdown/ reboot the computer if multiple
users are logged in and when there is only one user that user is able to
shutdown the computer?
Thanks,
Floris
