man issue

The file /etc/issue is an text file which contains a message or system identification to
be printed before the login prompt. It may contain various @char and \char
sequences, if supported by getty(1).


man dmesg

....
dmesg is used to examine or control the kernel ring buffer.

The program helps users to print out their bootup messages. Instead of copying
the messages
by hand, the user need only:
dmesg > boot.messages
and mail the boot.messages file to whoever can debug their problem.

Как то /etc/issue более в теме.
