mysql 5.5 skip innodb

In MySQL 5.5, it seems the skip-innodb option was removed so trying to boot MySQL with that option just makes it fail. Skipping InnoDB can save quite a lot of RAM and on lower end systems, this can be very useful. Here’s the new equivalent to skip-innodb in MySQL 5.5:

ignore_builtin_innodb
default_storage_engine=MyISAM
