Suppose a non-root user with sudo privileges executes a delayed shutdown (shutdown +10 or whatever) and logs out. Then, before the shutdown occurs, he wants to log back in and cancel the shutdown. The problem is that shutdown creates /etc/nologin, and login only allows root to log in when that file exists... is it possible to create an exception from this for a user?If not, what would be the best way to let a user initiate a delayed shutdown, then logging in and cancelling it at a later point?
Can I allow a non-root user to log in when /etc/nologin exists?
users;login;shutdown;not root user
