Jorge Castro and Mark Shuttleworth have both blogged about MAAS, or metal as a service and what it means for ubuntu and the server community. The development team is eager to get folks out there testing, using and giving feedback on MAAS, and have created a series of checkbox tests to help do so.
Check out this page on the wiki for more information. In short, if you've done any unity testing or manual app testing this cycle you will feel right at home.
When you respond 'no' to a checkbox test, apport should automatically launch and guide you through the bug filing process.
If you'd like to give feedback, comments or even patches, get in touch with the team on launchpad at https://launchpad.net/~maas-devel.
Don't hesitate to reach out to the wonderful folks on MAAS Team, the MAAS devel mailing list, or on IRC #ubuntu-server on freenode. Thanks for helping test ubuntu!
