Is documentation wrong?

Quick Start Guide for Percona XtraDB Cluster - Percona XtraDB Cluster
I used this^ link to set up mysql cluster in my lab.
First, debian package does not contains /usr/lib/tmpfiles.d/percona.conf, which means that dir /var/run/mysqld/ does not creates at server startup.
Than, I tried to bootstrap first node as described in Bootstrapping the First Node - Percona XtraDB Cluster, but got this:https://imgur.com/a/bCOpxDWconfs attached to imgur postWhat’s wrong with documentation? I did it literally as described in docs.OS: Debian 10, cluster version 8

Hi @ilya_romashev
I was not able to reproduce your issue.
 >First, debian package does not contains /usr/lib/tmpfiles.d/percona.conf, which means that dir /var/run/mysqld/ does not creates at 
/var/run/mysqld directory creates during package installation and all needed permissions should be set to this directory 

As for startup issue I tried several times but everything works as expected
