Hmm, interesting idea.

See below.  And if you can provide more ideas regarding the "why you
want to do this", we (have cc'd the larger dev team) may have some more
suggestions.

Quick tutorial:

    see <prefix>/images/README
	on how to create seed images

    see <prefix>/data/README
	specifically "images" section
	to determine how to name the files

    then <prefix>/cgi-bin/coe_bootimage would need to grok an "all"
    function, and <prefix>/cgi-bin/nph-* would need to know how to
    do "all" builds

    and finally the <prefix>/data/final* would have to be adjusted
    to present "all" builds

That said, it "could" be done.  We do have one other mechanim that
may be of interest to you as well (and as yet is undocumented, but
will be very soon).  It's called replay and can generate a boot
image based on the breadcrumb files from an already installed system.
It is conceivable to generate an ISO file from a USB deployed system
and vica-versa.  The draft use case can be found here:

Hope this helped,
