[rt-users] how does the best practical crew quickly deploy test machines?

[John Arends]

A week or two ago I posted asking about how people deal with CPAN 
modules when using an automated process to build RT machines, and it got 
me wondering, how does the Best Practical crew do it?

I imagine while testing you guys put up and take down hundreds of RT 
machines.

What is your build process? What OS do you run RT on? What tools do you 
use, etc?
