NOTES
nologin is a per-account way to disable login (usually used for system accounts like http or ftp). nologin(8) uses /etc/nologin.txt as an optional source for a non-default message, the login access is always refused independently of the file.pam_nologin(8) PAM module usually prevents all non-root users from logging into the system. pam_nologin(8) functionality is controlled by /var/run/nologin or the /etc/nologin file.
