Ensure /etc/motd is configured
Опис
The contents of the /etc/motd file are displayed to users after login and function as a message of the day for authenticated users. Unix-based systems have typically displayed information about the OS release and patch level upon logging in to the system. This information can be useful to developers who are developing software for a particular OS platform. If mingetty(8) supports the following options, they display operating system information: \m - machine architecture \r - operating system release \s - operating system name \v - operating system version
