Ok Sander I see the BIG problem but there's always a solution ;-)

Would you want to do this procedure before another one :
1/ Shutdown the mysqld (mysql server) using init script (something like /etc/init.d/mysqld stop) or if you cannot using the command "killall mysqld" (or "kill -9 yourprocesses") so you do not need to be root.
2/ go to your MYSQLINSTALLPATH/bin
and start mysqld directly with this command :
./mysqld_safe --skip-grant-tables --skip-networking
(nota --skip-networking is just for security, not necessary)

3/ another shell console
start the mysql client going to your MYSQLINSTALPATH/bin
and type : mysql (without any options)

4/type the following statements
mysql> flush privileges;
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('yournewpassword');

5/ try to connect with another client with your new password
mysql -u root -pyournewpassword

If you cannot do this procedure (but i would be very surprised)
The only solution i see (may be someone else could help you more) is to shutdown your actual mysql server, install another mysql binary in another directory and :
- start this new mysql server.
- stop it
(the first time root has no password)
- do a binary copy of your actualserverdatadir/mysql (or tar)
- then copy the newserverdatadir/mysql directory to your actualserverdatadir/mysql

- finally restart your actual mysql server and client (root has no password)



Hope this helps
Valerie
