As far as I can tell on Ubuntu Edgy with mysql 5.0.24 the variable 
controlling the binary logs is in /etc/mysql/my.cnf  (or 
/var/lib/mysql/my.cnf  or ~/.my.cnf  if it has been copied there).
The binary logs are not rotated but are expired according to the value 
of "expire_logs_days"
At least that's what happening on my system...
