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.
