Note that I'm currently working on a tool which will allow you to say:
"Here's a CD full of files and an 'image template' (created for a new
CD, also by my tool) - please fetch any new deb's and re-use the other
files from the old CD."
Eventually, I want to write a graphical user interface, but the tool
is useful even now, as an add-on for the current command-line
pseudo-image-kit. Expect a first release in a week or so.
Cheers,
Richard
