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

Error:
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.

Fix:
Fortunately, this is easy to fix:
rm /etc/profile.d/Z98-byobu.sh

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