in old systemd versions that happend when something used in namespaces
(ReadOnlyDirectory and friends) was a symlink instead a folder

the only expected symlink in that whole path is /var/run pointing to /run

and file a bugreport at Redhat, that should be /run to begin with for a
long time

anyways, this is not a systemd error, something on your environment or
files shipped wioth the distribution is broken
