Eventually I ended up doing this. For my purposes it seems to work well.
The deb files in the first six ISOs are being used to form the basis of
an archive on a USB stick and I was getting apt refusing to install a
handful of files because their checksums differed from what it expected.
I thought about Charles Curley's apt-cacher-ng suggestion but, while
having apt take care of everything was an attractive idea, it doesn't
quite answer my needs.
I took the md5sum.txt files on each ISO and, after a bit of editing, got
them in a single file.
md5sum `find -follow -type f` > md5sum.txt
gives me a file for the archive. 'diff -a --suppress-common-lines -y'
does the comparison of the two files.
