We have multiple servers with Debian, Ubuntu and CentOS. We decided, that we need to be able install our own non-binary and java packages to any of these servers using rpm, because CentOS our primary distro. But a lot of warnings about using rpm could be found in various Debian documents, and none of these documents covers what's bad in-deep.
What could go wrong, if we create our own rpm packages containing only .jar/.js files, pre-install/post-install/startup scripts and without any dependencies?
