Error/Fix: Disable byobu (screen) from automatically starting on login (EC2)

If you run Ubuntu 11.10 (Oneiric Ocelot) on Amazon EC2, you may notice an annoying “feature” that they enabled on this release. A byobu session is started when you login.

Fortunately, this is easy to fix:
rm /etc/profile.d/

Also fortunate, this will not be the case for future releases as it has been removed.
