As part of the last_orders() function we use an aditional function which produces information on the amount of disk space used on the image (so I can make sure they are no more than 80% full when burnt).
(run_finalise is run_customize but from last_orders; not used very much by us).
Feel free to include this function in nanobsd.sh if someone feels like it.

disk_usage () {
sync; sync; sync
set -- `du -sk $NANO_WORLDDIR/`
used=$1
set -- `ls -sk $NANO_DISKIMGDIR/_.disk.image`
size=$1
avail=$(( $size - $used ))
availp=$(( ${avail}00 / $size))
pprint 1 "disk usage: $used of $size used, $avail available ($availp%)"
}
last_orders () {
if test -f ${NANO_DISKIMGDIR}/_.disk.image; then
run_finalise
disk_usage
fi
}
