Here's an update on Canonical and Secure Boot:
"Canonical have today responded with plans on how they intend to approach the
SecureBoot situation to ensure that Ubuntu ‘works smoothly’ for users of
devices enabled with it.
Firstly, Canonical has generated an Ubuntu key that, once manually added to
affected systems, will allows users to boot Ubuntu.
‘Simple ways for enterprises and consumers to use this key‘ will be
announced in due course.
Ubuntu will also use a different kind of boot-loader for Ubuntu on SecureBoot
hardware – one not based on the traditional GRUB2.
