Hi Michele!

As you can see, now the creation of BOOT has to steps:
- First one: measure size using du under the umsdos/ext2 filesystem, and use
this size to create a first BOOT.raw (original behavior)
- Second one: measure again the size under the mounted BOOT.raw, and use it to
create the definitive BOOT.raw

Code from line 291 of mu script follows:

set -- `du -k -s $TREE/startup`


dd if=/dev/zero of=BOOT.raw bs=1k count=$ROOT_OFFSET >/dev/null 2>&1
eval mkfs.ext2 $MKFS_OPT BOOT.raw 2>&1 >/dev/null

mount -o loop BOOT.raw $mount_point >/dev/null 2>&1
rm -r $mount_point/lost* 2>/dev/null

cp -af $TREE/startup/* $mount_point

# Second step -> accurate size
set -- `du -k -s $mount_point`
umount $mount_point
dd if=/dev/zero of=BOOT.raw bs=1k count=$ROOT_OFFSET
eval mkfs.ext2 $MKFS_OPT BOOT.raw
mount -o loop BOOT.raw $mount_point
rm -r $mount_point/lost* 2>/dev/null
cp -af $TREE/startup/* $mount_point
umount $mount_point
