Display the motd file
pam_motd is a PAM module that can be used to display arbitrary motd (message of the day) files after a successful login. By default the /etc/motd file is shown. The message size is limited to 64KB.
The /path/filename file is displayed as message of the day.
Don't run the scripts in /etc/update-motd.d to refresh the motd file.
Only the session module type is provided.
This is the only return value of this module.
The suggested usage for /etc/pam.d/login is:
session optional pam_motd.so motd=/etc/motd
