Сценарий оболочки получает правильный PID

Я написал небольшую программу, которую хочу запустить как службу на Opensuse 11.3. Это из сценария init.d, он запускает мои процессы, как я хочу, но я не получаю правильный PID.

Что мне не хватает?

echo "Starting DHCPALERT"
for (( i = 1; i <= $DHCP_AL_DAEMONS; i++ ))
do
    var="DHCP_AL_$i"
    START_CMD="exec /sbin/startproc -p "$DHCP_AL_PID_DIR"p_"$i".pid -l "$DHCP_AL_LOG_DIR"log_"$i".log "$DHCPALERT_BIN" "${!var}" &"
    eval $START_CMD
    echo "PID: "$!
    echo "Command: "$START_CMD
done

приводит к

PID: 47347
Command: (/sbin/startproc -p /var/log/sthserver/dhcpalert/p_2.pid -l /var/log/sthserver/dhcpalert/log_2.log /usr/sbin/dhcpalert -i eth1 -c ./test.sh -a 00:15:5D:0A:16:07 -v )&

но pidof возвращает какой-то другой pid.

Если я попытаюсь выполнить его напрямую:

exec /sbin/startproc -p "$DHCP_AL_PID_DIR"p_"$i".pid -l "$DHCP_AL_LOG_DIR"log_"$i".log "$DHCPALERT_BIN" "${!var}" &

Затем я получаю ошибки:

startproc:  exit status of parent of /usr/sbin/dhcpalert: 1

Я полагаю, потому что я не избегаю переменных правильно?
