I think I might have discovered one reason why mythbackend was screwing
up.  I rebooted my machine and tried mythbackend again after rebooting:

camille ~ # mythbackend
2006-10-05 14:36:41.431 Using runtime prefix = /usr
2006-10-05 14:36:41.573 New DB connection, total: 1
2006-10-05 14:36:41.574 Unable to connect to database!
2006-10-05 14:36:41.574 Driver error was [1/2002]:
QMYSQL3: Unable to connect
Database error was:
Can't connect to local MySQL server through socket
'/var/run/mysqld/mysqld.sock' (2)

QSqlQuery::exec: database not open
QSqlQuery::exec: database not open
2006-10-05 14:36:41.633 DB Error (KickDatabase):
Query was:
SELECT NULL;
No error type from QSqlError?  Strange...
2006-10-05 14:36:41.688 Failed to init MythContext, exiting.

So I tried mysql:

camille ~ # /etc/init.d/mysql start
 *  ...
 * Starting mysql (/etc/mysql/my.cnf)
 * MySQL NOT started (0)
[ !! ]

I looked for logs:

camille ~ # ls /var/log/mysql
camille ~ #

camille ~ # cat /var/log/messages | grep 'mysql'

I can't find any logs as to why mysql won't start.  I can't make sense
of the /etc/init.d/mysql script.  Can anyone give me a hint as to why
mysql is not starting?
