Comment 4 for bug 1020022

From Michael's mail:

I was thinking the same thing - a pristine image plus the standard
build deps, then we add a little extra on top. Should cut the start
time from ~10 minutes to less than 1 and make it more reliable.

I've created the blueprint
https://blueprints.launchpad.net/cbuild/+spec/custom-ami-for-ec2 to
track the work on our side.

So, as there's good understanding and BP now, this bug can be closed.
