I looked into the flume service demo and one patch for ganglia. I was wondering if some docs describing the service installation lifecycle were available. I would be interested to now when [before, after]Bootstrap, Configure are called during the VM lifecycle procedure. My interest is to: - know where to define SecurityGroup rules (in ec2 dialect) - in flume it seems to be located in beforeConfigure while at that stage I would have assumed tthe VM to be already started - know if I can set-up fw rules involving external/local addresses - know how to decide in which order ServiceMasterHandler / ServiceNodeHandler shall be run (sometimes nodes need the master ip or vice-versa)
