I don't think that e.g. the postgresql or xendomains start scripts would fit well into that scheme. > But python or other bloaty scripting languages are not a solution and > completely unacceptable at this place. "Bloaty" is something that could be solved, don't you think? If python was split up in a base package that contained the directory structure, the binaries, the (small) documentation and only basic modules (with no additional requirements) and a package containing the rest of the modules, much of the (dep-)bloat wouldn't be an issue if init scripts (ehh modules) would be limited to that basic set. With the set of modules I would choose, such a python-base package would have less dependencies than bash and only account for roughly 2.6MB on the disk as well -- bash takes up about 5.1MB.
