Yes, thank you.
I have been able to increase to the capacity of the
partition ' mulinux.img'.
But you do not mention some details that can confuse
to a novice... like I.

That means that I cannot increase the size more than
the free space in FAT partition.

Mmmmh. I must create the filesystem first. As I do not
have nor idea, simply I looked for 'clone' script and
copy the line where it formats loop filesystem.
But it is the most interesting question here:
I have had to increase the size of the partition
because although my system mulinux only has 8MB of
archives, in fact occupy 20MB, due to the internal
fragmentation. So I think that I would have to format
the new one with a smaller cluster size.
I think that this is important because you try to
maintain the distribution as small as possible.
Oh, I must go...
See you later.
