What is cfengine?

from :

 Cfengine, or the configuration engine is an autonomous agent and a middle to
 high level policy language and agent for building expert systems to
 administrate and configure large computer networks. 
 Cfengine is designed to be a part of a computer immune system. It is ideal for
 cluster management and has been adopted for use all over the world in small and  
 huge organizations alike.

while says:

 What is Cfengine? A set of tools that administers and configures computers 
 according to the instructions in its configuration files, which describe the 
 desired characteristics of system components using a high-level language.
 (Paraphrased from Aeleen Frisch, Essential System Administration, 3rd Edition, p. 921.)

 cfengine is controlled using a declarative language that allows you to describe the way you want various characteristics of your system to be configured.  

It is somewhat Prolog-like in that the language is declarative, rather than procedural.

It manages differences between related systems using a notion of classes. That allows you to distinguish between different flavours of Unix so that configuration is done differently on Debian versus SGI Irix. Classes also allow you to distinguish between hosts in YOUR environment that have different purposes, so that rules can be applied differently for database servers versus end-user workstations versus application servers.

cfengine and fai

There are plans to migrate FAI's cfengine-scripts over to cfengine2 (which adds a client/server-based model to cfengines capabilities), but there still needs some testing to be done.

To use cfengine2 in Your scripts, replace


in Your v1-scripts by

 #!/usr/sbin/cfagent -Kf

and run a normal install. For debugging, change -Kf to -vKf or add any of the debugging flags.

Please give us feedback. Either here, via the mailing-list or on / #fai
