I don't have an answer to this, but wanted to chime in because I have
had the same issue in the past.  I had once heard a friend tell me that
he used to create ISO images in this very way in Linux by mounting an
ISO image on a (Linux) loop device and then copy files to the image.  It
seems like it could be a flexible and convenient way to quickly create
an ISO image at random, but I've never been able to get FreeBSD to mount
and ISO image rw using either vnconfig or mdconfig.  Maybe there are
some practical considerations that we are overlooking?
