nologin - prevent unprivileged users from logging into the system
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.
