        if [ ! -d "$datadir/mysql" ] ; then
            # First, make sure $datadir is there with correct permissions
            if [ ! -e "$datadir" -a ! -h "$datadir" ]
            then
                mkdir -p "$datadir" || exit 1
            fi
            chown mysql:mysql "$datadir"
            chmod 0755 "$datadir"
            [ -x /sbin/restorecon ] && /sbin/restorecon "$datadir"
            # Now create the database
            action $"Initializing MySQL database: "
/usr/bin/mysql_install_db --datadir="$datadir" --user=mysql
            ret=$?
            chown -R mysql:mysql "$datadir"
            if [ $ret -ne 0 ] ; then
                return $ret
            fi
        fi
