The file "/etc/securetty" contains a list of all tty's on which root login
is to be allowed. Normally, this lists only virtual consoles for security
reasons. The *better* way of logging in as root from a remote terminal is
to login as a normal user and then use the "su" command to become root only
when you *have* to. It's not good practice to be root all the time, since
if you screw up it can make your system unusable for long periods of time.

The most reliable method (because it even works on dumb terminals) is simply
to put 26 empty lines at the top of your "/etc/issue" file. Since getty will
display "/etc/issue" before displaying the login: prompt, your screen will be
clear of other debris.
The more elegant method is to include the "clear" command in your shell's
logout file (if it can do that). BASH uses "~/.bash_logout". This file is
executed *after* you type "logout" or "bye".
Sorry, but I don't know the answer to the Seyon question.
