slackware does that (from /etc/rc.d/rc.6):
...
# Turn off swap:
echo "Turning off swap."
/sbin/swapoff -a
/bin/sync

echo "Unmounting local file systems."
/bin/umount -v -a -t no,proc,sysfs

echo "Remounting root filesystem read-only."
/bin/mount -v -n -o remount,ro /

# This never hurts:
/bin/sync
...
