FreeBSD port: mysql-server-5.1.29, won't boot/start

Hello people,

I've been running a FreeBSD server for a while right now, and for 'bout a week the mysql-server startup script located at /usr/local/etc/rc.d/mysql-server won't start the MySQL Server...

After some digging through the processlist, configuration files and start up scripts I concluded that FreeBSD assembles the command

Code: 
su -m mysql -c sh -c "/usr/local/bin/mysqld_safe --defaults-extra-file=/var/db/mysql/my.cnf --user=mysql --datadir=/var/db/mysql --pid-file=/var/db/mysql/ervert.pid"

in order to start the MySQL server through the start up script.

When I strip the su -m mysql sh -c part and run it manually it's all working fine. So I've no clue where to look next.

/etc/rc.conf does have the mysql_enable = "yes" entrie.

--
The official mysql-server script won't give me an error, when you run it by hand, or let the machine run it during boot up; it just opens up a new shell (it's an SH shell), running with the userid mysql; I just don't seem to get it...


Do you guys have any clues left for me? Having to start the MySQL Server by hand each time the server reboots, is slowly getting on my nerves...
 
Does that command return with return code 0 when you run sh -xv /usr/local/etc/rc.d/mysql-server start?

Tenx DutchDaemon,

When I try your command it says in the end; a return value off 0... I guess the main problem has something to do with the fact, it's starts a new shell environment with the mysql user running it.

Your command gave me a debug clue :) I'll have a new try this afternoon; now I've to patch up something completly different :)

Tenx again Dutch Daemon!

After some more digging I've found out, that if I can solve the next riddle; my current startup problems will vanish into thin air ;)
(it all comes down to the 'su -m' part ... located within the first part o'the command)

When I run the next two commands on different FreeBSD machines
Code: 
su -l svn -c 'echo foo' (works on all machines)
su -m svn -c 'echo foo' (won't work on my own machine, works on others)

Is there anybody out there, whom has the answer to my little riddle ... Right now I'm completly clueless ...
