NAME
       nologin - prevent unprivileged users from logging into the system

DESCRIPTION
       If  the  file  /etc/nologin  exists and is readable, login(1) will allow access only to root.
       Other users will be shown the contents of this file and their logins will be  refused.   This
       provides a simple way of temporarily disabling all unprivileged logins.
