So, if I have a "networking" bundle, I'd have a "networking_vars" bundle which sets a variable like "netmask" to either "netmask_default" or "netmask_override". Then in the networking bundle, I just reference "networking_vars.netmask" so all the logic is hidden. That doesn't simplify all of your concerns, but does potentially free up one pass through the promise while variable values stabilize. I've been meaning to extend that approach and try making a parametrized bundle which takes the varaible as input (say, "bundle agent overrideable(varname)"), but I've been too busy to figure out how CFEngine handles variable namespacing when I call the same bundle name several times. _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
