I've started using Amazon EC2 with Aegir's multiple server setup and its sweeeet.  I can add a new server to my Aegir setup in like 2 minutes.

My bash script

Here is the script: http://pastebin.com/hHnTDtzs

I've tested this script with ami-3e02f257.   These are its specs:

• Ubuntu 10.04
• 32bit
• EBS Store (allows this to be "micro" compatable and easy to backup/clone.)

I don't see why the script wouldn't work with x64... I just didn't test that.

What it does

• Installs everything you need plus git and nano
• Forces php to be 5.2 rather than 5.3 using approach #3 here.
• Does almost everything you need to do in the manual aegir install for using the server as an slave host.  Sets memory limits, comments bind-address, creates aegir user, creates aegir_root mysql user, etc...
• Installs pecl uploadprogress
• Installs Dru
