Documentation not taking wsrep.cnf into account

Description

The manual https://www.percona.com/doc/percona-xtradb-cluster/LATEST/configure.html#configure suggests adding wsrep related settings in /etc/my.cnf for RedHat/Centos installation or /etc/mysql/my.cnf for Debian/Ubuntu.

However, at some point, PXC packages come with configuration layout having dedicated wsrep.cnf file, which may actually overwrite the settings used in my.cnf. For example under Centos 7:

 

[root@node1 ~]# cat /etc/redhat-release CentOS Linux release 7.1.1503 (Core) [root@node1 ~]# rpm -ql Percona-XtraDB-Cluster-server-57.x86_64|grep cnf /etc/my.cnf /etc/my.cnf.d /etc/percona-xtradb-cluster.cnf /etc/percona-xtradb-cluster.conf.d/mysqld.cnf /etc/percona-xtradb-cluster.conf.d/mysqld_safe.cnf /etc/percona-xtradb-cluster.conf.d/wsrep.cnf

The new layout has to be taken into account as now the documentation is misleading.

There are comments under the doc page already reporting this issue, also forum questions, like https://www.percona.com/forums/questions-discussions/percona-xtradb-cluster/52590-new-5-7-cluster-3-centos-7-nodes-don-t-join
