Fedora has no packages relying on it. It has nothing to do with initramfs, /run (/var/run) will always be empty at bootup. Packages who rely on pre-existing content in /run (/var/run) need to ship tmpfiles (man systemd-tmpfiles) instructions to populate /run (/var/run) at bootup before the services are started. Real services which startup as root, ideally create the needed content themselves, and not use tmpfiles. Kay </blockquote></div>
