I am new to linux, so this may be a very simple question.
I have created a modified ami using the ubuntu 11.10 as a starting point. All of the tutorials I have found say that to save an instance you must be the root user, but I have only been able to log in as user Ubuntu. How do I log-in as the root user, or gain root authority, on Ubunty 11.10 so I can bundle and save my modified image?
Thanks in advance!
