Packages which install files in /run (/var/run) need to be fixed.
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.
