I'm having problems enabling binary logging on mySQL 4.1.20
to my.cnf, mysql fails to restart, with the following error in mysqld.log:
091112 03:36:37 mysqld started /usr/libexec/mysqld: File '/var/log/mysql/tts_db.000001' not found (Errcode: 13) 091112 3:36:37 [ERROR] Could not use /var/log/mysql/tts_db for logging (error 13). Turning logging off for the whole duration of the MySQL server process. To turn it on again: fix the cause, shutdown the MySQL server and restart it. 091112 3:36:37 [ERROR] Aborting 091112 3:36:37 [Note] /usr/libexec/mysqld: Shutdown complete 091112 03:36:37 mysqld ended
Whilst looking at it to ask this question, I may have stumbled on the answer, but I'll check anyway – I can't restart the server until tomorrow morning.
The mysql directory (/var/log/mysql) is owned by root. Is this problem because the mysql user that the server runs as doesn't have the correct privileges for creating a file in the directory?
Here's the complete my.cnf ( i know the log-bin is commented out – this is the current one)

In general on Linux systems, an Errno 13 means Permissions Denied or Access Denied.
What's the output of
Does this match with your MySQL user?
If not, suggested solution (providing mysql is your mysql user and mysql is your group):
