I don't know the specifics of working with Amazon EC2.

When working on my own machines, I've done minimal installs on some new 
machine, and then created a bunch of spare partitions which mirror the 
partitions on my existing machine.  I then use dump/restore to duplicate 
entire partitions from the existing machine to the new one.

I then fix up /etc/fstab in the root partition on the new machine to 
match the locations of all the copied partitions on that new machine.  I 
probably fix up a few other config files, such as /etc/rc.conf (to get a 
different IP address, and set a different hostname).  I then reboot the 
new machine into the copy of '/' which was duplicated from the existing 

I'm afraid I don't have the time to write up more details, but hopefully 
that provides the basic idea.
