ifconfig

The server I administrate, inconveniently enough, has a dynamic IP address assigned by DHCP. The convenient counterbalance, though, is that it happens to be set up about two feet from where I sit. I know how to edit /etc/issue to show different values before the login prompt is delivered to the display, but I'd like to know if it's possible for /etc/issue to display the current IP address of eth0 (re-evaluated at boot time) so that I can see it and then ssh in without having to log in to run ifconfig.
