Hi Guys, Sorry to resume this discussion, but I find the current situation unfriendly to most developers. I understand there's a need for specific configurations, but it seems to me that this has taken one step too far for most developers. Further more, I expect to see such fundamental concepts being initially discussed here, and not settle with a technical ack, only to be a part of a thread called: "Error on starting webadmin". In this context I expect the verified flag to mean "This was discussed and verified with contributers in the relevant list". My use case is exactly what Juan describes, but I think the resolution should be different. ie- contributers should be able to git clone and once they setup jboss & postgres they should be able to have something running. We cannot assume /etc is a location contributers can access. Think of university students who would like to see how ovirt works using university's machines. In the past they may have had issues with JBoss, but that's already handled by profiles. So there's really no need for oVirt to ask them more than that. I know UI plugins are using this infra, but remember that the plugins are completely optional and should not block basic operation. Some more concerns this issue raises are related to release versions; What happens when we need to support more than one jboss and/or release version? So here are 2 options we should consider in order to allow local config without additional requirements: 1. Use defaults. System should boot and start in whichever way we decide without anything else needed. Local configuration can override these defaults if it exists, but it should simply work. 2. Use local JBoss profile. Have everything we need in my-standalone.conf and start running jboss with a local profile. This conf file may be generated or copied once when running mvn -Psetup We can also inject the relevant environment variables to the global standalone.conf as we do for debugging, but this cannot be used in the students use case, unless we have host-level config. I know many are still in vacation due to the holidays, so we should wait for a few more days before making a final decision. Still feel free to ack / nack / suggest your own.
