not to stir disagreement, rather to reinforce it (since I just realized that
I  a previous email just to monty, and not to the list..)

chef and debs are not actually at odds.

we're using debs + chef + crowbar to do automated testing of our full
solution. The breakup is more or less:
- crowbar - automates pxe boot and basically all provisioning steps,
including the steps that follow below
- debs - install and configure services on a single machine (i.e. register
services)
- chef - based cookbooks and on configuration created by crowbar hooks up
multi machine deployment into working clusters.

the driver behind this setup is that debs are not that suited to configure a
multi node deployment or react to machines added to a cluster.
We have this setup executing on both kvm and actual physical hw.

So, totally +1 with Monty -- we're talking past each other a bit....
