I'm working on a project involving EC2 and I'm having a difficult time wrapping my head around this concept.

With EC2 instances, will non-EBS backed volumes (standard EC2) survive a reboot of the OS? For example, I have an Ubuntu instance. If I type "/sbin/shutdown -r now", will I lose all data on the drive not in the AMI? I understand that if I terminate the instance via the tools or the control panel, I lose everything, but I can't find a concrete answer to the restart issue.

An extra gold star goes to anyone who can link to documentation clearly explaining this. ;)

Thanks for your time!
