And fun fact: not only RHEL 7 and thus CentOS 7 does so, but too Debian 
9 and Ubuntu 16.04 LTS (I have no newer test install of that distro).

And frankly speaking, I don't see any indication that this violates with 
the FHS and that /var/run must persist reboots.

Can we please end this stupid discussion? Enough arguments have been 
exchanged to make clear that packages are broken if they ignore the fact 
that /var/run content is ephemeral.
