Right. rpm-ostree uses ostree, which introduces /usr/etc which are the pristine default config files. /etc is 3-way merged by ostree. One of the major benefits of this that I really love is `ostree admin config-diff` - at any point we can show you machine-local changes from the default, and it's trivial to reset back to defaults without redownloading a whole RPM. The semantics of /etc are also one of the things that is very different between ostree and other image based update systems, including the "systemd upstream vision" introduced a while back, which is basically that /etc starts empty, can be populated dynamically, but is otherwise not touched across system upgrades. The core problem with this is it introduces a new major hysteresis point which is your copy of /etc is mostly from the initial installed OS version. You don't get *new default* config files, and even worse, packages that drop config files still linger around in this model. I personally think ostree's handling of /etc is one of the things that makes it feel much more like a Unix system than other image based update systems. There's no hidden agenda - the goal is to support image based updates as well as client side snapshots, factory reset, etc. And we're shipping today versions of Fedora that do a lot of this, and we want to continue to improve it. _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
