Comments - Installing MariaDB with yum/dnf

Just to clarify and add a bit more information:

The post install scriptlet uses the following commands to create an "array" :

mysql_dirs=(`/usr/sbin/mysqld --verbose --help 2>/dev/null|sed -ne \
's/^\(basedir\|datadir\)[[:space:]]*\(.*\)$/\2/p'`)
basedir="${mysql_dirs[0]}"
datadir="${mysql_dirs[1]}"
  # datadir may be relative to a basedir!
if expr $datadir : / > /dev/null; then
  mysql_datadir=$datadir
else
  mysql_datadir=$basedir/$datadir
fi

Observe the following:

root@server [~]# /usr/sbin/mysqld --verbose --help 2>/dev/null|sed -ne \
's/^\(basedir\|datadir\)[[:space:]]*\(.*\)$/\2/p'
root@server [~]# 

Notice how it's empty. That meanst that:

mysql_datadir=/

And thus it runs: chown -R mysql:mysql /

Just wanted to clarify. Again, let me know if you need more information from me.
