Introducing cfengine
Good configuration is a seriously hard problem. Worse, it just seems to get
harder and harder as time goes on. Managing a mixture of old and new computers
and making sure they all do what they're supposed to do becomes harder
exponentially and is known to cause hair loss, high blood pressure,
social deficiencies, and in some cases, death.
Anchor's ninja-sysadmin Jamie Wilkinson has the
answers; and he's managed to keep our computer's configurations humming
along nicely. In this series of articles, he'll let you in on some secret server
kung-fu that's keeping our network of systems manageable.
