MariaDB and XtraDB/InnoDB plugins

In my vps, I thought of switching from MySQL to MariaDB (using Monty's repository for Debian Squeeze). Copying over my.cnf from MySQL to MariaDB, I saw that the new config file (the one from the MariaDB package) does not mention any plugins commands like the old one from MySQL, where I loaded the InnoDB plugin. Now, I understand that XtraDB has become the default ACID storage engine in MariaDB, in place of InnoDB. Since I find MariaDB site's documentation lacking in this area, do I need to put something extra in the new my.cnf to activate XtraDB or is it active by default? show plugins returns this: MariaDB [(none)]> show plugins; +--------------------------------+--------+--------------------+---------+---------+ | Name | Status | Type | Library | License | +--------------------------------+--------+--------------------+---------+---------+ | binlog | ACTIVE | STORAGE ENGINE | NULL | GPL | | mysql_native_password | ACTIVE | AUTHENTICATION | NULL | GPL | | mysql_old_password | ACTIVE | AUTHENTICATION | NULL | GPL | | MyISAM | ACTIVE | STORAGE ENGINE | NULL | GPL | | partition | ACTIVE | STORAGE ENGINE | NULL | GPL | | ARCHIVE | ACTIVE | STORAGE ENGINE | NULL | GPL | | BLACKHOLE | ACTIVE | STORAGE ENGINE | NULL | GPL | | CSV | ACTIVE | STORAGE ENGINE | NULL | GPL | | FEDERATED | ACTIVE | STORAGE ENGINE | NULL | GPL | | MEMORY | ACTIVE | STORAGE ENGINE | NULL | GPL | | Aria | ACTIVE | STORAGE ENGINE | NULL | GPL | | MRG_MYISAM | ACTIVE | STORAGE ENGINE | NULL | GPL | | PBXT | ACTIVE | STORAGE ENGINE | NULL | GPL | | PBXT_STATISTICS | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | InnoDB | ACTIVE | STORAGE ENGINE | NULL | GPL | | INNODB_RSEG | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_BUFFER_POOL_PAGES | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_BUFFER_POOL_PAGES_INDEX | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_BUFFER_POOL_PAGES_BLOB | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_TRX | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_LOCKS | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_LOCK_WAITS | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_CMP | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_CMP_RESET | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_CMPMEM | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_CMPMEM_RESET | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_TABLE_STATS | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_INDEX_STATS | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | XTRADB_ADMIN_COMMAND | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_SYS_TABLES | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_SYS_INDEXES | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | INNODB_SYS_STATS | ACTIVE | INFORMATION SCHEMA | NULL | GPL | | XTRADB_ENHANCEMENTS | ACTIVE | INFORMATION SCHEMA | NULL | GPL | +--------------------------------+--------+--------------------+---------+---------+ 33 rows in set (0.00 sec) What do I understand from the output above?
