[ovirt-devel] Packaging: Rationale for some split packages

I work on inclusion of Vdsm into Debian. I don't know what are the reasons for having separate `infra', `xmlrpc', `yajsonrpc', and `jsonrpc' packages. Could you please provide rationale for having each of those packages, separated from `vdsm' and `vdsm-python'? I need to put proper explanations into package descriptions so that the users know whether they should install/remove those packages or not. Thanks, Milan
