not a big issue, anyway nothing related with kernel development.

here is the relevant part of my /etc/rc.d/init.d/halt (RH):

----------------

echo "Remounting remaining filesystems (if any) readonly"
mount | awk '/ext2/ { print $3 }' | while read line; do
mount -n -o ro,remount $line
done
echo "^G"
sleep 1
echo "^G"
sleep 1
echo "^G"
# Now halt or reboot.
echo "$message"
[ -f /fastboot ] && echo "On the next boot fsck will be skipped."
eval $command -d

----------------
