When the system startups and /etc/init.d/mysql is executed with "start"
parameter, something goes wrong and pidfile and socket are not created
under /var/run/mysqld.

I use a fresh and default mysql-server-5.0 installation.

Syslogs says that "/etc/mysql/


"ps" output:

-------------------


Note that "netstat" says that there is a UNIX socket which in fact
doesn't exist!:
------------------
~# netstat -panx | grep mysql
unix  2      [ ACC ]     STREAM     LISTENING     4707     2512/mysqld
~# ls -l /var/run/mysqld/
total 0
---------------


Of course, "/etc/init.d/mysql stop" doesn't work since no pid file is
found.


If I kill mysqld process manually (and mysqld_safe) then I can start the
server with "/etc/init.d/mysql start" and then it starts correctly (it
generates the pid and socket in /var/run/mysqld).

The same problem occurs also in a 64 bits system.
