It should only be called from programs that explicitly opt in to it. Perhaps is should be /usr/libexec/system-python rather than /usr/bin/system-python, to drive the idea home. > This sounds like a really bad idea.

Right. Every package using system-python would need to explicitly disable the automatic Python requires, and add the system-python ones. > Technically, there is one for independent Python module packages > coming in RPM upstream that is currently disabled by default (in fact, > I've got a pull request to improve it based on feedback from the > Python SIG as well as Mageia[1]), but I don't think that is currently > designed to handle the kind of complexity this is going to introduce. > > How in the world would we handle such a dramatic departure from how we > currently package Python? It's a change designed for a few system tools that can accept the limitations. we can make Python-less containers and cloud images smaller. Normal Python packages would be unaffected. So I don't think it's a dramatic departure. -- Petr Viktorin -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
