Infrastructure Management

Mike has a whole pile of useful entries on infrastructure management for Linux and Debian with puppet and other tools. Also check out this quick look at puppet.

A Look at Conary

Conary: An innovative second-generation package manager

I agree with the review that all the conary jargon is very confusing.  Seems to be worth the effort though as conary might provide in the long run a good system for not just building software appliances, but a useful system for managing a large number of Linux systems.
