The /etc/nologin file might be what you want...
If the file has contents, they are echoed to the terminal of the user
attempting to login (use this to tell the user why they cannot log on at
that time, and when they can expect login service to return).
It is generally used to keep people off a system while the sysadmin does
maintenance (because as you say, users never stay off when told to). The
/etc/nologin file gets removed on reboot.
