No. Binary packages are not for development, they are for operations. Source and XX-devel packages are for development. In fact, DEBs and RPMs are the best currently known way of deploying services, being easy to build, to install, having vast tooling around them, and being flexible enough to fit most of the deployment scenarios. > Modern systems and services are deployed as images, file system trees, or the entire “userland” of the operating system, as seen in containers. Except containers are vastly underdeveloped with regard to be a packaging systems, are mixing packaging and running a networked VM, and can't always be used to run a service. > If you’re running apt-get update or yum update on a production system you’re asking for trouble. If one's not running `apt-get upgrade' on production systems, then he's asking for trouble. Please don't let some random developer who have never seen sysadmin's job in any greater scale tell you how to deploy and manage systems.
