issue - Issue identification file
The /etc/issue file is a freely formatted ASCII file. If present, the
getty program reads this file and writes its contents to any terminal
spawned or respawned from the /etc/inittab file prior to writing the login
prompt string specified in the /etc/gettydefs file.
If the /etc/issue file is present and the /etc/issue.net file is not, the
telnetd daemon reads this file and writes its contents over a new telnet
connection prior to starting the login dialog.
Use this file to store messages that are longer than the message field for
entries in the /etc/gettydefs file.
You must be aware of the size limits of all potential output devices
as you create /etc/issue messages. Some devices (for example, small
screens) might not hold the messages you enter into the file and will
truncate the messages.
/etc/issue Specifies the path name for the file.
Commands: getty(8), telnetd(8).
