I believe there is a way to sandbox the upgrade now, so it can be "test
driven" and rolled back if the user is not happy.

Rick, Marjo and I are actually hoping to take this a step further in Lucid
by making it possible to do this in the cloud, instead of locally in KVM.
We've already done this for Server Edition, where you can start an EC2
instance using any daily build without even downloading anything.
We want to make the same experience possible with Desktop Edition. No
downloading ISOs, no installation, just the latest development code running

We get a tremendous amount of feedback and testing of Desktop Edition during
development, but we could do with more early user testing of server
milestones. I think a cloud solution is even more compelling for servers,
since they're command-line operated. Why download hundreds of megabytes of
OS, and spend time installing it, when you just to see it running for a

That's interesting. I wonder what the performance is like for a typical
