wsrep_sst_mariabackup acts on mysqld_settings even when it's not used

wsrep_sst_mariabackup has the following lines:

    if [[ $ssyslog -ne -1 ]];then 

        if $MY_PRINT_DEFAULTS mysqld_safe | tr '_' '-' | grep -q -- "--syslog";then 

            ssyslog=1

        fi

    fi

So when it finds a

section in the configuration files with a

option, it will also make the SST script log everything to syslog, regardless of actual

configuration section settings.

Now the problem is that this even happens when

settings from the configuration.

Especially if that someone is us, and still delivers a /etc/mysql/conf.d/mysqld_safe_syslog.cnf file ( or /etc/mysql/mariadb.conf.d/50-mysqld_safe.cnf in 10.5 packages) with contents

[mysqld_safe]

skip_log_error

syslog

as part of Debian and Ubuntu packages.

Due to this files content the [sst] settings for sst-syslog, sst-log-archive and sst-log-archive can't be changed. sst-syslog will always be enabled, and the later two settings are ignored when it is. Even explicitly setting

whill not change this due to the sst script logic.
