just upgraded from mysql 3.23.? to 4.0.13.
Though the mysql startup script says ok, it actually fails launching mysqld
I just replaced /usr/bin/safe_mysqld with /usr/bin/mysqld_safe in /etc/init.d/mysql
and it worked.
I can upload the patch if needed.
you didnt update your initscript.
sorry to have bothered you with this.
