The purpose is to put a special message in it, such as:
"System down due to unfriendly Gnomes. It will be back up
at approximately 5:00 PM EST" or some such helpful thing.
If you have no special message, the system supplies a default.
Once Upon a Time, in a career far away, we had several login
programs, they all operated in this way.

And, let us say, your system was operated by the militantly French?
They might wish the message to NOT be in English, for example.
The logins I was familiar with would suppress the standard
message if you supplied a custom one.
