Below is a little script to mount and extract an image in a way that will
allow for editing and repackaging of the lrp modules.
It uses tmp files but eventually creates (replaces) a directory called
lrp-super, which contains a directory for each lrp module and the root
filesystem per the package below it. (see the second find output below)
I plan to borrow some code from lrcfg to repackage and add some new code
to manage the other critical files and reconstruct the image.
I wanted to post this now for comments. Here is an example of the
(extend image) command line usage and the nature of the result.
