run script before reboot o halt

[ferrillo]

Good Morning,
I have made a script to log the computer startup and shutdown (shutdown).
I am interested in modifying this script so that when I do a manual reboot or halt it will also register.
In this way I know when it is restarted by a manual reboot, by a power failure, by a shutdown or by a halt.
That is, when I shutdown it works for me, but when I do reboot or halt, it doesn't. how could i do this?
This is my script:

#!/bin/sh

# PROVIDE: rmiregistry
# BEFORE: LOGIN
# KEYWORD: shutdown

# Añadir a /etc/rc.conf xxxxx_enable="YES"

. /etc/rc.subr

#rmiregistry_enable=${rmiregistry:-"NO"}

name=rmiregistry
rcvar=`set_rcvar`
pidfile="/var/run/${name}.pid"

start_cmd="start"
stop_cmd="stop"
restart_cmd="restart"
describe_cmd="describe"

load_rc_config $name
start() {
        if [ ! -f $pidfile ] ; then
                echo -e "Starting services: $pidfile"
                echo $$ > $pidfile
                find /usr/local/etc/rc.d/server.log -type f -size 1M -exec rm '>
                date +'Start server: %F %T'>>/usr/local/etc/rc.d/server.log;
                #echo -e "rmiregistry is now running on $pidfile"
                #rmiregistry &
                #echo $! > $pidfile
                #echo "."
        else
                echo "It appears $pidfile is already running. NOT starting!"
        fi
}

stop() {
        if [ ! -f $pidfile ] ; then
                echo -e "It appears $pidfile is not running."
        else
                echo -e "Stopping services: $pidfile"
                date +'Stop server: %F %T'>>/usr/local/etc/rc.d/server.log;
                kill `cat $pidfile`
                rm $pidfile
        fi
}

restart() {
        stop;
        start;

}

describe(){
        echo "Escribe en log el inicio y apagado"
}

run_rc_command "$1"

Thanks for the help.

That is, when I shutdown it works for me, but when I do reboot or halt, it doesn't.

shutdown(8) runs the rc(8) scripts and gracefully stops all services, halt(8) and reboot(8) do not.

     The halt and reboot utilities flush the file system cache to disk, send
     all running processes a SIGTERM (and subsequently a SIGKILL) and,
     respectively, halt or restart the system.  The action is logged,
     including entering a shutdown record into the user accounting database.

Systems logs this though, you can find it in last(1) and /var/log/messages.
