Comment 2 for bug 248067

You mean "kern.log"? There are only the messages:

AppArmor: AppArmor initialized
AppArmor: AppArmor Filesystem Enabled

My MySQL data files are in /var/lib/mysql. The ISAM tables in /var/lib/mysql/mysql. However, I switched (for other reasons) to InnoDB tables. The file permissions are:

drwxr-xr-x 3 mysql mysql 4096 2008-07-16 07:56 .
drwxr-xr-x 62 root root 4096 2008-07-13 12:36 ..
-rw-r--r-- 1 mysql mysql 0 2008-07-13 12:36 debian-5.0.flag
-rw-rw---- 1 mysql mysql 18874368 2008-07-15 22:27 ibdata1
-rw-rw---- 1 mysql mysql 5242880 2008-07-16 07:56 ib_logfile0
-rw-rw---- 1 mysql mysql 5242880 2008-06-25 21:41 ib_logfile1
drwx------ 2 mysql mysql 4096 2008-07-15 11:17 mysql
-rw------- 1 mysql mysql 7 2008-06-25 21:41 mysql_upgrade_info

In my.cnf, I only added

default-character-set = utf8
default-storage_engine = innodb
