Comment 11 for bug 1316475

We're looking at this. The general rule in cloud-init should be "enabled by default if and only if there is no negative side effects". The one exception is the EC2 metadata service (it polls and has very annoying timeouts). However, its generally configured to be last, so all others have failed at that point.

We'll see if there is some way we can determine that we're running on CloudSigma and if so, then block on ttyS1. If not, go on quickly.
