There are a few reasons to do this. First, systemd changed to refuse mounts on symlinks, and hence if one *wants* "/tmp-on-tmpfs", one would need to write a different `sysroot-tmp.mount` unit. Second, the original rationale for having this symlink was that if you had multiple ostree stateroots ("osnames"), it's nicer if they had the same `/tmp` to avoid duplication. But in practice today that's already an issue due to `/var/tmp`, and further the multiple-stateroot case is pretty unusual. And that case is *further* broken by SELinux (if one wanted to have e.g. an Ubuntu and Fedora) stateroots. So let's fully decouple this and make `/tmp` a plain old directory by default, so systemd's `tmp.mount` can become useful. Now, things get interesting for the case where someone wants a physical `/tmp` that *does* persist across reboots. Right now, if one just did a `systemctl mask tmp.mount` as we do in Fedora Atomic Host's cloud images, you'd get a semantic where `/tmp` stays per-deployment, which is weird. Our recommendation for that should likely be to set up a bind mount for `/tmp` → `/var/tmp`. For now, this stays an option to ensure compatibility; if FAH Cloud images want to stay with "physical /tmp", then we'd have to change the kickstart.
