Hi Nicolas,
I have mysql-server-core-5.5 installed because of a dependancy from KDE 
(kdepim -> kmail -> kdepim-runtime -> akonadi-server -> akonadi-backend-mysql 
-> mysql-server-core).  I also have mysql-common installed, but *not* mysql-
server-5.5.  mysql-server-core-5.5 and mysql-common are both at version 
5.5.23-2 and I just upgraded both from 5.1 a few days ago.

The only config file I can see is /etc/mysql/my.cnf (attached).  (The users 
have no .mycnf (or whatever the name is) files.)  It seems to be unchanged 
from the one shipped with mysql-common.

Below are my experiments and results.  As a quick summary, it looks like 
/usr/sbin/mysqld fails when /etc/mysql/conf.d is not present, but works when 
it is present even if it is empty.  The mysql-server-5.5 package ships 
/etc/mysql/conf.d (and the file mysqld_safe_syslog.cnf inside): I think a 
simple solution to the problem would be for mysql-server-core-5.5 package to 
ship an /etc/mysql/conf.d, either empty or with mysqld_safe_syslog.cnf inside.  
(I think a better (upstream) solution would be for mysqld not to fail if that 
directory is not present...)

1. On starting /usr/sbin/mysqld (as a regular user or root) from the command 
line I get the error:

$ /usr/sbin/mysqld 
/usr/sbin/mysqld: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 2)
Fatal error in defaults handling. Program aborted

There is no apparent log file in /var/log, in $HOME, or in the directory in 
which the command was run.

This is the problem that kept amarok from working correctly for me.

2. If I made the empty directory /etc/mysql/conf.d:

$ /usr/sbin/mysqld 
120515 17:48:11 [Warning] Can't create test file /var/lib/mysql/lenny.lower-
120515 17:48:11 [Warning] Can't create test file /var/lib/mysql/lenny.lower-
/usr/sbin/mysqld: Can't change dir to '/var/lib/mysql/' (Errcode: 2)
120515 17:48:11 [ERROR] Aborting

120515 17:48:11 [Note] /usr/sbin/mysqld: Shutdown complete

It's the same when run as root.  Again, there is no apparent log file.

This solves the problem with amarok.

3. I also made the empty directory /var/lib/mysql:

120515 17:49:53 [Warning] Can't create test file /var/lib/mysql/lenny.lower-
120515 17:49:53 [Warning] Can't create test file /var/lib/mysql/lenny.lower-

120515 17:49:53 [Note] Plugin 'FEDERATED' is disabled.
/usr/sbin/mysqld: Table 'mysql.plugin' doesn't exist
120515 17:49:53 [ERROR] Can't open the mysql.plugin table. Please run 
mysql_upgrade to create it.
120515 17:49:53 InnoDB: The InnoDB memory heap is disabled

120515 17:49:53 InnoDB: Completed initialization of buffer pool
120515 17:49:53  InnoDB: Operating system error number 13 in a file operation.
InnoDB: The error means mysqld does not have the access rights to
InnoDB: the directory.
InnoDB: File name ./ibdata1
InnoDB: File operation call: 'create'.
InnoDB: Cannot continue operation.

Running this as root is the same but without the 3 warning lines at the 
beginning.   Again, no logs.

This looks like it things are working correctly, but with no database files to 
access in /var/lib/mysql.

4. After removing the two empty directories I created, /etc/mysql/conf.d & 
/var/lib/mysql, I installed mysql-server-5.5 and its dependencies (mysql-
client-5.5 & libdbd-mysql-perl).  Everything worked as expected: root could 
start mysqld but a regular user could not because of the permissions on 
/var/lib/mysql.  /etc/mysql/conf.d was created.  The logs in /var/log/mysql* 
are strangely empty.

5. I purged mysql-server-5.5 (and mysql-client-5.5 & libdbd-mysql-perl).  
/etc/mysql/conf.d was removed, so back to step 1.  (/var/lib/mysql was not 
removed, presumably to avoid deleting data.)

Please let me know if I can provide anything further.
