I know there's few better subjects for bikeshedding after vim vs emacs than "what should be in /etc/motd, /etc/issue and how should they interact with logins (ssh, console and xorg/gui)" - but how does this "break boxes"?
I guess for consistency, as update-motd seems to be installed by default(?) and the motd is called in /etc/pam.d/login by default - xmotd or something similar should also be installed to make sure that everyone is pestered by the message of the day...?
