We all know that InnoDB is the default engine as of MySQL 5.5 but ...
for some reason an extra configuration file zentyal.cnf is included in MySQL's conf.d
directory when installing mysql server package in Ubuntu 13.10.
This can really throw you as your choice of engine in your create table ... engine=innodb;
statements are completely ignored.
Was there a good reason for adding zentyal.cnf? I will report this as a bug on Ubuntu's Launchpad.
