[9fans] usb/disk nvram and pxeload

[Skip Tavakkolian]

if i pxeload a cpu and want to be able to use an nvram partition on a
usb disk (i.e. nvram=/dev/sdXX/nvram - once it is partitioned &
formated). it seems i also must change boot/boot.c to add the 'partfs
&& fdisk -p && prep -p' after usbd has started. is this correct?
