Конфигурация Linux md изменяется после перезагрузки

В Linux (Не знаю, работает ли это и в Solaris):

#!/bin/bash

if [[ $EUID > 0 ]]; then # we can compare directly with this syntax.
  echo "Please run as root/sudo!"
  exit 1
fi

BS=100M
MNT=/mnt/tmp
FILE=${MNT}/mem-hog
FS_SIZE=8G
LOG=${0}.log-$(date '+%Y%m%dT%H%M%S')
SLEEP=5s

function onExit {
  test "mountpoint -q ${MNT}" && umount ${MNT}
  echo "Bye!" | ts | tee -a ${LOG}
}

trap onExit EXIT

mount -t tmpfs -o size=${FS_SIZE} none ${MNT} || exit $?

[ -f ${FILE} ] && (rm ${FILE} || exit $?)

COUNT=0

while [ true ]; do
  COUNT=$((COUNT + 1))
  echo -e "\n>> Allocation step #${COUNT} <<\n" | ts | tee -a ${LOG}

  dd if=/dev/zero bs=${BS} count=1 2> /dev/nul 1>> ${FILE} || exit $?

  echo "" | ts | tee -a ${LOG}
  free -m | ts | tee -a ${LOG}

  echo "" | ts | tee -a ${LOG}
  df -h ${MNT} | ts | tee -a ${LOG}

  sleep ${SLEEP}
done
