This is exactly the sentiment I was looking for- and as our aim is to continue to maintain very homogeneous groups of software servers, we may not even get into the cfengine/puppet/bcfg2 etc... apps for quite some time- our scripted installs and updates should hold us for at least the next year.
It's the boot and install parts we need to focus on- perhaps months from now I'll post back with notes on what we did.
Now it's up to us to go sort out the tools' options!
Thanks Thomas, and Dave!
