Again thanks for the pointers and concerns . 3.1.0 has the -b option. I have
written something similar for cfengine2 a long time ago. I have quarterly,
hourly and daily bundlesequence and have define some special classes that i
defined with -D and they only executed a defined bundle, eg debian security
upgrade. That is very useful for cf-runagent.
