I just setup a Turnkey-Magento-12.0 instance in Amazon EC2...  

I had previsouly setup a Turnkey-Magento-12.1 Instance and its working fine, but I needed to go back to Magento 1.6 instead of 1.7.

Well After the 12.0 Instance came up I can connect via SSH... but it did not run the "First Run" script that lets me setup the passwords, etc. 

Is there a way to manually do that or were there default passwords for root in the older Turnkey 12 version?

Thanks.
