Users and groups created when installing some packages (avahi, usbmuxd) are not deleted along with its removal. Is it related to https://archlinux.org/todo/pacman-hooks-systemd-sysuserstmpfiles/ and requires some changes? Or should I always delete them manually? Hello,
If you decide, that you no longer need a user or a group, you have to manually delete it. This has to be a conscious decision, which is not something pacman or packages can do. I can’t locate authoritative information right now, but I believe the linked TODO entry from 2017 was related to replacing manual invocations of `systemd-tmpfiles` and `systemd-sysusers` with the corresponding drop-in configuration files. See commits cd35d646⁽¹⁾ and 072e646d⁽²⁾ as examples. ____ ⁽¹⁾ https://gitlab.archlinux.org/archlinux/packaging/packages/apache/-/commit/cd... ⁽²⁾ https://gitlab.archlinux.org/archlinux/packaging/packages/mariadb/-/commit/0...
