I forgot to reply to your second question. Cfengine's design will cause it to converge to the state defined in your policy over time. So depending on what's in your policy, it will likely take several agent runs before a system converges to the defined state. Separating promises into bundles is useful from an organizational perspective but should have no effect, other than the order in which bundles are run, on the convergence of your systems to the policy-defined state.
Mark wrote a great paper a while back, fairly technical, about Cfengine's convergent nature. See "A Tiny Introduction to Cfengine" at http://cfengine.com/pages/whitepapers. It's more centered on Cfengine 2 but the philosophy of convergence described is essentially the same.

Within each bundle, it evaluates the promise types in the following order (from section 2.8.1 in the reference manual): vars classes interfaces processes storage packages commands methods files databases services reports Within each bundle, it evaluates the above list of promise types up to 3 times in order to deal with potential dependencies, e.g. define var V1, define class C1 based on V1, define var V2 based on class C1, etc. Does that help?

The code in a bundle doesn't go top -> down? it first does the commands, then the packages then the commands and so on? 2. I've to run cf-agent multiple time until every promise in it is kept, is this usual? maybe i have to split this in different bundles? many thanks in advance nicolas _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine This electronic communication and any attachments may contain confidential and proprietary information of DigitalGlobe, Inc.
