Public bug reported:
I installed Jaunty (mythbuntu) yesterday and tweaked my mysql
configuration to have the server use InnoDB. When I then ran
mysql_convert_table_format on a database, apparmor started logging
permission issues on temporary tables.
The perms on all mysql directories are fine and when I turned apparmor
off MySQL stopped complaining.
