if [ "$1" -ge "1" ]; then
    /sbin/service mysqld condrestart >/dev/null 2>&1
fi

(granted, I should have added a || : there - done)

I'm not sure we're talking about the same thing. My bug was about the init 
script not the spec file

# /sbin/service mysqld condrestart
Usage: /etc/init.d/mysqld {start|stop|status|reload|condrestart|restart}
# /etc/rc.d/init.d/mysqld condrestart
Usage: /etc/rc.d/init.d/mysqld {start|stop|status|reload|condrestart|restart}
#

I said that in the init script you put the condrestart function, but you don't 
do

case $1 in 
   condrestart)
    ...

Doh. Fixed. Thanks,
